CMS Rewrite troubles: Request exceeded the limit and 500 server error

[محروم.كوم]

I've an infinite list of that errors in my apache log

Quote:
Request exceeded the limit of 10 internal redirects due to probable configuration error


it makes my server to be really slow and at my users shows a lot of error 500 page...

There is any that I can do to fix it?
Just to make my server faster i forced LimitInternalRecursion 1 but this isn't a good solution.

I've vBulletin 4.0.3 Suite (I need to update to last one)...

I have too much troubles with vBulletin 4, really too much, if that situation don't change I think to go back to 3.8.x and don't upgrade my license again __DEFINE_LIKE_SHARE__
