Problem Change Performance Will Generate Error 500

[laurent0071]

Hi All,

 

I need help, I have spent days trying to solve this issue but I failed.

 

Any change that I am doing in the performance tab even if I click on empty the cache I will have an error 500 for both the front office and the back office.

 

Any settings I will change for the performance page will lead to that error 500.

 

I found how to solve the error 500 : by deleting the file called class_index.php located in the cache directory but this is doesn't resolved the fact that I cannot change any performance settings

 

 

Can you please help me to solve this problem.

 

I compared both files class_index.php before and after the error.

Here are the difference :

 

On the left it's the file class_index.php that contains error when I try to change any performance

How to solve this problem so I can perform changes in the Performance page ?
