HTTP 500 error on admin setting page

[Anna]

Hi,
I have a problem on my installation of 2.6 whenever I try to save the changes I do in the admin/ settings page I get a HTTP 500 error. I have tried both on a selfhosted server and a webhotel but the reslult is the same a HTTP 500 error, And mod_secuity is not installed on my self hosted server, not sure about the hotel.

what does your error log say? is button_config.php write-able? (chmod 666)

The error log says nothing, and button_config.php is 777

This is my error_log file and it's set for debug I also turned on error logging for php and I upload my error_log file in this post

got it thanks, I see a couple interesting things here I will address first thing in the morning. Unfortunately I dont believe I see anything related to an "Internal Server Error 500" here, but I see you have suHosin installed and that could be a place for me to start digging, will let you know what I find.
