FuarKalu Posted May 29, 2019 Share Posted May 29, 2019 Greetings, I have upgraded my PrestaShop from 1.6.1.6 to 1.7.5.1. and thereby, had a total crash. Visiting the page results in Server Error 500. The Admin-Page is restored, but importing the CSVs to recover Shop-Data produces errors ("Rewrite Link für (ID: null) wurde neugeschrieben als friendly-url-autogeneration-failed.") Furthermore the 500 Error occures even while navigating through the Admin menus. Link to comment Share on other sites More sharing options...
El Patron Posted May 29, 2019 Share Posted May 29, 2019 you should restore your shop from backup and then create a devcopy of your shop to do initial upgrade test. you also need to turn on ps debug mode to get underlying issue (500) error as this is generic.
