[Forum] Apache error log Request exceeded the limit of 10 internal

[chrisd]

Hello,

Our apache logs were full of error like:
[Sun Oct 30 17:59:18 2011] [error] [client 66.249.71.105] 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.
----
My hosting provider investigated further and found that this error is due to our vbulletin install. More specifically, as you can see below, the vbulletin .htaccess seems to be adding .php to requests containing blog.php.
Extracts from the rewrite log:
[09/Nov/2011:18:15:47 --0700] [forum.frenchfriends.info/sid#102cb830][rid#10492bb0/initial] (1) [perdir /home/french/public_html/forums/] internal redirect with /blog.php.php [INTERNAL REDIRECT]
[09/Nov/2011:18:15:47 --0700] [forum.frenchfriends.info/sid#102cb830][rid#10497630/initial/redir#1] (1) [perdir /home/french/public_html/forums/] internal redirect with /blog.php.php.php [INTERNAL REDIRECT]
[09/Nov/2011:18:15:47 --0700] [forum.frenchfriends.info/sid#102cb830][rid#104701b0/initial/redir#2] (1) [perdir /home/french/public_html/forums/] internal redirect with /blog.php.php.php.php [INTERNAL REDIRECT]
etc....

Here is a copy of our .htaccess:

Any help to stop these errors is welcome. Thanks!

What version of vb are you running? And are you using the correct htaccess file that came with that version (it was changed around 4.1.6, I believe)?

[Paul K]

With the download of VB there is a 'default' .htaccess provided, if you run only the forum for example use the .htaccess in the forum folder, not the other one. This was the mistake I made the first time

[chrisd]

I'm running 4.0.6.

I just downloaded 4.1.7, I do not see a .htaccess. Where is the default .htaccess located.

I had also installed the blog add-on back in version 3. It does not exist anymore with version 4. Wondering if that could be creating this issue?

Thanks!
