Request exceeded the limit of 10 internal redirect

Question

My website has been slowed down a little last couple of days. I've looked into my error log and found lots of these:

[Mon Sep 30 00:09:53 2013] [error] [client 66.249.66.205] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

How can I find what is causing this?

It seems a loop around index.php, with the exception of the last one which is an image, most likely linked within one of my pages (not index).

I'm using codeigniter, which is a mvc framework and everything goes trough the index.php file, so it's a bit harder to understand where it goes wrong.

Apparently it has something to do with .htaccess (it's been mentioned in couple of blogs).

Here is my .htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ index.php?/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    # Submitted by: ElliotHaughin

    ErrorDocument 404 index.php
</IfModule> 
AddType image/x-windows-bmp bmp

I did some changes to my .htaccess (basically I've removed to top conditions before the last block) and now I get this:

Now it seems there is the img directory in the mix, but I dont have that directory at all. There used to be a subdomain which I used for images with this address.

img.mysite.com => mysite.com/files/images/

I don't use it anymore because of some slowness and complications. Now I just use the real path to images.

Why do i get this subdomain in the loop? I don't have access to the guy who configured this server. Could it be some config / setting that he has done?

Answer 1

Maybe it is a dummie awnser, but I just empty my .htaccess and configure permalinks again. Everything works after that.
