Prestashop 1.7 /admin error 500

[o..o]

Hi,

I just installed fresh Prestahsop 1.7.2 and I'm getting error 500 when trying to access /admin.
Frontent seems to be working ok.

Server log shows nothing.

Even when I set:

define('_PS_MODE_DEV_', true);

I'm still getting:
 

500 Application error

The server encountered an internal error and was unable to complete your request. This may be caused by application error or request timeout. If this error is permanent, please contact webmaster.

 

What could be the problem?

Thanks

Would you please post the last 10 lines of your error log and the last maybe 20 lines of your access log directly after you made an access attempt?

And what happens if you change the folder name so something other than admin?
