HTTP Error 500 - can not save anything

[Voyteack]

Hello,

I have a problem with HTTP 500 Error. I tried to look for the solution here and there and nowhere was the one that could help me.

The problem is that I can not Save any changes, it started with Maintenance mode, which I could not turn on. After saving HTTP 500 Error popped up (img PH1.png)

. The same thing happened when trying to save logo of the shop.

 

I asked hosting to explain what happenned as usually http error 500 refers to hosting, however the answer from them was that 

handler php does not freeze, the http 500 error is sent to the browser by the software itself (prestashop in this case, to be exact version 1.6.2)

Can anyone help me with it?

Hi, 500 is generic, please enable PrestaShop debug mode to see underlying php error.

Thank you for a quick answer, however it did not show any bugs. The same error pops up, http error 500, nothing more. Do I need to check it somewhere else? I just turned false to true.

Thank you in advance for your help

in addition, I could not find any solution through google..

Haha, sorry but it is funny to post things myself with new conclusions I have gone through some spanish forums and found out that there are many problems with version of php attached to your profile (hosting). I had a brand new version of php and changed it to much lower version and the logo was saved properly, so it looks as solved, I hope it will last.

Hope that solution will be useful for someone else.
