Error 500 -Admin panel

[Danny23]

Hi, 

i have apache, mariadb, phpmyadmin etc on my localhost..

i installed latest presta on my pc 1.7.6.3

everything was ok. Perfect.

 

After some time of learning and playing with it, my admin panel crashed - Internal server error 500 ...

Frontend still working. Changes immediately before crash - installed some modules, disable caching for some CSS study, disable apache optimization, javascript cache..

 

This is error from php_error.log from php server

What i was trying

- disable modules in databse ps_module table (changing 1 to 0 at new installed modules)

- clear var/cache folder

and nothing happen.

I can get back into backend when i allow debug mode (_PS_MODE_DEV_', true) in defines.inc.php, but when i allowed all caching and optimizing back and set debug mode back to false, error 500 still there. So i cant determine where is the change, that trigger into 500 error. 

Ofc, i can install whole new prestashop and start my playing/learning again from start, but its much better understand whats wrong for me.. 

Sorry, my engl not perfect, you can see
