You don’t have permission to access /index.php on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

After that I have tried to search some related info from the net to find the solution how to 403 Forbidden Error, they asked:-
- to check any change of the permissions to access that directory.
- to take a look at the .htaccess file in that directory.

Unfortunately the above solutions do not work for me, then I started to think how to solve 403 Forbidden error by myself. This is what I have been done, see below:-

1. I reinstalled WordPress by overriding the existing file
2. Found that /index.php cannot be override, then I checked the File Permissions for index.php and found that the file attributes have been changed, I confirmed that this is the problem caused 403 Forbidden error.
3. I have tried to change the file attribute to 644, unfortunately I can’t changed it directly.
4. I have no choice but to delete /index.php file from that directory and upload the NEW index.php to that directory again.
5. All right, finally my blog is displayed properly and the problem has been solve.

If you have facing this problem in future, perhaps you can try my methond to solve 403 Forbidden error, good luck to you!

1. Type about:config into the Firefox URL/address bar and hit ENTER. (You will be warned that you might void your warranty if you change some advanced settings, just click the button “I’ll be careful and I Promise!” to go ahead)

2. Search the following Preference Name/entry and set their values to “true” by double-clicking each one of them.

network.http.pipelining
network.http.proxy.pipelining

3. Next, find this entry too and double-click and set the value to 8.

network.http.pipelining.maxrequests

4. Right-click anywhere inside the config page and select New –> Integer. Name it nglayout.initialpaint.delay and set the value to “0″.

5. Right-click anywhere inside the config page and select New –> Integer. Name it content.notify.interval and set the value to “500000″.

6. Right-click anywhere inside the config page and select New –> Integer. Name it content.switch.threshold and set the value to “250000″.

7. Right-click anywhere inside the config page and select New –> Boolean. Name it content.notify.ontimer and set the value to “true″.

8. Right-click anywhere inside the config page and select New –> Boolean. Name it content.interrupt.parsing and set the value to “false″.

You should be able to notice the speed improvement immediately after applying the above tweaks. Remember, you should also disable the “firefox addon” that you don’t use often, this will help to improve the speed of Firefox loading during the startup.

After that I tried to search some info from search engine, there was a fix on some plugins to check page rank. For example, those people who are using SEOQuake to check google page rank, you can following the below steps to fix the problem.

1. Go to SEOQuake Preferences
2. Select PageRank then Edit
3. Paste THIS instead of what is already there!

[NAME]=Google pagerank
[TITLE]=PR
[URL_R]=http://toolbarqueries.google.com/tbr?client=navclient-auto&ch={gchecksum}&features=Rank&q=info:{url|encode}
[REGEXP]=Rank_.*?:.*?:(\d+)

4. Clear Firefox cache and restart firefox, done!

Sadly to know that my favorite firefox plugin Search Status was unable to fix because I can’t find any solution to solve the problem. I believe that we have to wait until the next update of Search Status to fix the google page rank showing problem. Anyway, you still can use Google Page Rank toolbar to check the google page rank, please don’t worry!

There are several solutions that other bloggers have provided and guild us how to solve the problem of Internal Server Error, unfortunately none of them can really help me. Most of the posts saying that most probably is due to the corrupted of .htaccess file. They asked to backup the current .htaccess and then create and blank .htaccess file and upload again. Hmmm.. this method can’t work for me!

I guessed there must be something happen on my hosting, if not why all of my blogs having the same error since I didn’t change wordpress themes, upload new plugins, update posts and etc. When the time I login to my cPanel page, I get shocked to see the Cpanel CPU and Memory Usage is full. Yes, this is the problem caused all my blogs cannot be displayed due to the memory allocation to the files. 

After that, I tried to contact my hosting technical support, they replied that it may be is due to huge of plugins used on my blogs, and asked me to take down those unusable plugins. What the hell?! I don’t have many plugins on my blogs, all the while my blogs are working fine for many years, of course I can’t accept this reason. Beside that, my technical support also suggest me go to change VPN server to support all my current blogs. I really want to fuck him because I only have few blogs without using high bandwidth, why I need VPN server? Really stupid technical support!!!

I know Internal Sever Error is most likely caused by low memory limit on my server this time, but I have nothing to do how to lower down the memory usage, then I just wait until second day. When the time I wake up from my bed, all my blogs were working fine, the cPanel CPU and memory usage is back to normal. Thanks god!

Anyway, if you found Internal Server Error 500 on your WordPress blog, I advise you to check the CPU and memory usage on your cPanel account first, if the CPU and memory usage is working fine, the most probably you can try to check your .htaccess file or plugins usage on your blog.

Normally I prefer using Filezilla to upload or download files, but sometimes I will found some error like 421 too many connections (8) from this ip. This may sometimes be accompanied with a “Delaying connection for 5 seconds due to previously failed connection attempt” error. So how to solve this type of problem? Do you ever see this error before?

When you see error 421 too many connections (8) from this ip, then you go to File > Site Manager. Select “Transfer Setting” tab, and then simply click on the checkmark box next to “Limit number of simultaneous connections” and you can keep “1″ in the box. (refer below image)

After you have limited the number of simultaneous connections to 1 but you still get the error 421 too many connections (8) from this ip, switch of your modem and on it back, and you may need to completely shut things down so the previous connections are killed.

Important: Don’t download thing when you upload or download files using Filezilla. and don’t surf net using browser too. Normally I seldom get the error 421 too many connections (8) from this ip.

Copy and paste the following code into your template, for example sidebar.php, replace feedburner-id with your Feedbuner username. This script will grab you the feed count in numbers.

//get cool feedburner count
$whaturl="http://api.feedburner.com/awareness/1.0/GetFeedData?uri=feedburner-id";

//Initialize the Curl session
$ch = curl_init();

//Set curl to return the data instead of printing it to the browser.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//Set the URL
curl_setopt($ch, CURLOPT_URL, $whaturl);

//Execute the fetch
$data = curl_exec($ch);

//Close the connection
curl_close($ch);
$xml = new SimpleXMLElement($data);
$fb = $xml->feed->entry['circulation'];
//end get cool feedburner count

Now paste this anywhere you want and it’ll display a Feedburner subscriber count in text.

echo $fb;

POP SSL required? Yes
User name: Your Windows Live ID, for example yourname@hotmail.com
Password: The password you usually use to sign in to Hotmail or Windows Live
SMTP server: smtp.live.com (Port 25)
Authentication required? Yes (this matches your POP username and password)
TLS/SSL required? Yes

I’m using Windows Vista, I found that I can’t even uninstall XAMMP and this caused WAMP cannot be run properly. I have tried to find solution from Internet but unfortunately I can’t get any help from that. I nearly give up to give it a try, I was thinking that to format pc and install back Windows again in order to solve this problem.

After that, I suddenly figured out that normally Windows Vista requires us to run software and application that we install as administrator. That’s right! All you need to do is to run xampp-control.exe as administrator (right click xampp-control.exe file and choose Run as Administrator), and then stop the Apacha and My SQL, then you can uninstall without any problem.
