WordPress upgrade problem: encountering blank page
I upgraded to WordPress 3.01 and to my surprise, I found out that my blog is in blank page state.
After some trial and error, I found out the plugin wp-table is causing the problem.
If any one else is having the same blank page issue, follow the guidelines here:
- Under /wp-content, rename plugins to plugins-old (we removed all plugins installed)
- Navigate to your wordpress website. It should be working fine now.
- create a new folder plugins
- now move your plugin folder under plugins-old back to plugins, 1 by 1 or group by group, whichever you prefer.
- Retest your wordpress blog everytime you done movement.
- By this way, you should be able to identify which plugin is outdated and causing problem to your wordpress.
If your wordpress is still showing a blank page after step (1), you should google for other workaround as the plugins are not the one that causing the problem.
Computer auto power on after shut down/power off
Few months ago, my sister's PC is having a miserable problem: The computer auto power on after 1 - 2 seconds after it has been shut down / powered off. To stop it from powered on again and again, I have to disconnect the power from the PC (switch off power, unplug power cable)
This happens no matter how I power off the PC - shut down/hibernate/stand by from Windows, manually shut down by pressing the power button, either in Windows or DOS.
Not only it brings inconvenience. The hardware could deteriorate faster than ever with sudden turn on without getting enough "rest", especially hard disk with priceless information that cannot be recovered back.
Since I am the one who install the CPU, MOBO and RAM (perhaps an apprentice with less experience), I think there might be some problem with my installation.
To be safety, I unplug the most precious hardware - harddisk before I proceed.
Among the methods to fix the problem I have done:
- Hardware part
- changing the Power Supply Unit (PSU)
- reading Motherboard manual and re-cabling the connectors from casing to motherboard
- changing memory stick to different slot
- recheck all the PSU cables to motherboard
- Unplug all the keyboards, LAN cable, mouse, monitor, USB device, etc (they might send signal to wake up PC perhaps?)
- Software part
- Checking BIOS settings in every aspects
- Load BIOS settings to default/optimized/fail safe
- Update BIOS firmware to the latest version
But non of this helps. Some might think that I have to reformat the OS. I am assured that OS is not the problem. The hard disk is unplugged and how can this problem to have contact with Windows?
So what could be the problem? It troubles me for a few months. And yesterday, I relook again into the casing, and notice a neglected part of the motherboard - the battery. I removed the battery and BINGO, the CPU can be powered off normally! Even I load the optimized settings of BIOS, the PC just work fine.
So, remember to reset everything to the very initial states if you can't solved the problem. This recall me in the old time, my Sony Ericsson 610z is auto reboot when scrolling in contact list. A master reset just solved the problem. It looks like a hardware problem but in fact it is the software part problem:)
Malaysia Web Hosting Review (2)
It has been a terrible week for me since the beginning 1st January.
The web hosting service I am using - HIVE, is having problem since 1st of January, when the website is frequently facing problem of database inaccessible. It took 2 days for HIVE to realise that the problem might be caused by part of the harddisk failure. They make an announcement saying that the server is estimated to be back online on the next day (4th January). However, the estimation is delayed for a few times, and the server is able to be back online until evening of 6th January. However, due to 2 hard disks of them are having problem at the same time, they can only retrieve the database backdated to 20th December. This means that more than 10 days of data is gone!
Furthermore, their support is unsatisfied as always. I was having hard time contacting them through e-mail, as when I replied them through e-mail, I could not get any replies. I have to go to their website to open ticket in order to reach them. I asked them for several times what is reason that I cannot reach them by replying their support mail, and the question was simply ignored. Furthermore, if you can get a reply from them in a few hours, that is considered as a fast response for them. Their technical support is always MIA.
My personal thought on HIVE is that, they have limited staffs and resources, possible a small organization with limited budget. This is the impression they imprinted on my mind, as a customer being 3 years with them.
Alternatively, I look for internet-webhosting again. They have a promotion with greater specification at lower price plan. As you know, internet-webhosting has great support team. Though not all the support personals have great knowledge, but they can response you in a short time. Mostly in less than 10-30 minutes. If you are in luck, you may reach their Level 3 technical assistant to solve the problem. I decided to subscribe to their Surfers Plan which allow me to host 15 domains at lower price and greater bandwidth (50GB/month). This is incomparable among the hosting packages in Malaysia, base on my research.
Of course not all the things are perfect; internet-webhosting have to train their technical support to be more technical aware, or pass to a more capable person if they can't solved the problem. I have bad experience as my IP was blocked from viewing my own website. They claimed that it is caused by the IP is connecting to FTP without port number. However, I never connect to FTP with the two IPs I am using last time.
I questioned them if the IPs are simply blocked. There is no reason for me to host my website on the server which simply block visitors. Unfortunately their level 2 technical support failed to give explanation for me.
PPStream 流氓软件？
看来 PPSTREAM 也要被我列入流氓软件列表了。之前就觉得奇怪，为什么开ppstream 竟然比开迅雷还要吃带宽。如果内网有任何人看ppstream，其他人根本不用做东西了。
多亏 netlimiter , 我才发现原来ppstream是多么可恶的。。。
下载的速度 = 19.91 kB/s
上载的速度 = 72.50 kB/s
难快看ppstream不觉得很顺，但是整个上传的带宽却被它占用。如果只是刚开机的时候这么跑法还ok，但跑了20-30分钟还是这样，只好把ppstream关掉。
关掉就没事了吗？问题还没解决呢。还有一个 PPS 网络加速器，也在占用您的宽频，即使你关掉PPS！加速加速，听它放屁，把我的带宽变成龟速就有。都没看PPS了还要PPS加速来干什么？上传竟然搞到 22.37 kB/s！
PPStream 利用普通视窗用户不能测查流量的弱点，进行如此不道德的勾当，真是没天理。
简单快速自制伴奏 – Part 1
有一首你很喜欢的歌曲，偏偏这首歌并不是该原唱歌手的主打歌之一，不论有没有受其歌迷的注目，该歌曲的KTV 始终没被唱片公司考虑在内。这时候如何呢？
运气好的话，到网上搜一搜，可以找到歌曲的消音伴奏。但若没有好心人制作该伴奏，又应当如何？
这里提供一个简单容易上手制作消音伴奏的方法。开始前，请先准备以下的软件/插件：
安装之后，打开 Winamp，从菜单中点选 Options > Preference 。相同地你也可用 Ctrl + P 。
在设定选项视窗中，点击 Plug-in >
在插件选项中，点选DeFX v0.97。
DeFX0.97
要消音，点选Karaoke的 【On】按钮，所播放的歌曲即刻就被消音了。你可以在 【level】、【filter】、【band】、【width】调整所适合的消音程度。
千千静听的使用者也可用类似上述的方法达到消音的效果。
WordPress plugin upgrade failed: solved by Core Control
I have been using WordPress 2.7.1 for a few months. In the very beginning of the first two months, I was able to upgrade the plugin, with some chances of failure. But lately, I was totally unable to upgrade the plugin in WordPress through built-in FTP. It just failed miserably, with the message: Download failed.: name lookup timed out.
Plugin upgrade failed
As this problem has been happening with the chance of 100%, I suspect that this might be the problem from Web Host side, probably caused by incorrect setup or configuration. Until today I googled the problem, I eventually found a working solution, thanks and redirect by CarltonBale to WordPress Trac.
Here is the detailed solution of mine:
- Download Core Control plugin (version 0.8 as of 3th August '09)
- Install Core Control plugin from Plugins > Add New
- Go to Core Control Settings page. Enable HTTP Access Module.
- "External HTTP Access" fore will come out. Go to the page.
- Under Manage Transport, choose "Test Transport" for cURL.
- If it return the result: name lookup timed out, then disable the cURL transport.
Final look of core control settings
And finally, plugins updates is working. Going to reduce the growing number beside Plugins tab 
Passing object from PHP to Flash using JSON
To pass an object with JSON serialized value to Flash, download as3corelib and extract to your project folder accordingly.
The example below show a person.php with class person and the corresponding as3 script to get data from php script, decode it and output accordingly.
//flash.php
class Person {
var $surname;
var $lastname;
}
$person[0] = new Person();
$person[0]->lastname = "Bryant";
$person[0]->firstname = "Kobe";
$person[1] = new Person();
$person[1]->lastname = "Owen";
$person[1]->firstname = "Michael";
echo json_encode($person);
//actionscript 3
import flash.net.URLRequest;
import flash.net.URLLoader;
import com.adobe.serialization.json.JSON;
var loader:URLLoader = new URLLoader();
loader.load(new URLRequest("http://localhost/flash/person.php"));
loader.addEventListener(Event.COMPLETE, onComplete_handler);
function onComplete_handler(event:Event) {
var person:Object=JSON.decode(event.target.data);
trace(person[0].firstname + " " + person[0].lastname);
trace(person[1].firstname +" " +person[1].lastname);
}
The trace output should look like this:
