How to fix 500 - Interner Serverfehler


G.S

Recommended Posts

Since a few days we try to install the PrestaShop 1.7.4 on our server.

We use PHP 7.2 (with CGI + opcache). The frontend works so far, but if we try to open

shop/admin/index.php?controller=AdminOrder      everything is fine.

The problem begins if I try a link which starts like:

shop/admin/index.php/module/manage?_token

shop/admin/index.php/product/catalog ....

Than we will get a 500 - failure

The error.log shows:

"AH01215: error: cannot stat directory"  and "End of script output before headers: php72-cgi,"

Does anyone knows what to do ?

Thank you for your help.....

thank you for your help,

the problem is, that I can't open the performance link

Is it possible to activate the function on antoher way ?

 

 

Oh!  yes there is, it requires FTP or file manager on your hosting to access the files directly.

Here is old post on how to enable debug mode via file system:

Thank you El,

but it seems that this only helps for the frontend. The backend has still the same error 500 page.

Is it possible to switch on the debug function for the backend ?

 

Hi, check the error log on your hosting then.  Some errors will never be displayed, i.e. mod_security for example.  But enabling debug mode works same front office or back office.

Hi El,

this is what I get from the error.log,  if I try to open shop/preferences :

[cgi:error] [pid 5390] AH01215: error: cannot stat directory: (shop/admin/index.php/configure/shop), referer: shop/admin/index.php?controller=AdminOrders&
[cgi:error] [pid 5390] End of script output before headers: php72-cgi, referer: shop/admin/index.php?controller=AdminOrders

Do you have an idea ?

(shop/admin/index.php/configure/shop)

does not look to be correct path and the error tells us that it does not existing or we do not have permissions

maybe you have change to AdminOrders via 3rd party module?  

on performance page you can disable 3rd party modules and/or overrides.  You can disable them retest, this will tell you 'maybe' if issue with 3rd party module/override.

note: my 1.7.4 does not  have 'shop-->preferences' navigation
