[Cristian965]

Hello,

Please help me with the following issue:

- when use the front store (web store) to place an order I got and error 500 in normal mode, but no error in debugg mode.

The error message is shown after I choose the payment option and click on "place order".

I use Prestashop 1.7.8.6 and php 7.3

The BO work ok in either modes, normal or debugg.

I'll wait your help.

Best regards,

Hi,

you can check the error 500(or exception that caused it) in the error log in the folder var/log/prod

also clean your cache folders manually by deleting the folders var/cache/prod and var/cache/dev

also you should test it using php 7.4

Have a nice day, Leo.

Hi Prestachamps,

Thank you for your prompt answer.

I switched to 7.4 and delete the cache folders (actually rename them prod.old and dev.old), but didn't solved the problem.

I wasn't able to check the error log, because I didn't found the folder var/log/prod. In my case var folder content only cache folder, logs folder (with zitec_emkp folder included) and sessions folder.

Do you have other advises?

Best regards,

Cristian

Hi,
I think I solved. It was a module installed to connect my web store to a marketplace. I disabled this module and it's working now just fine.
Thank you for your help.
Best regards,
