[Qnik]

Hello, I have a big problem. I tryed to upgrade Prestashop 1.6.1.11 to version 1.6.1.12 using  1-click upgrade. But error was shown (I migt error with database) Now I have problem with my eshop. It shows error 404 on main page. Function rollback make nothing. Is possible to find files backup? I don't create it before upgrading. I have backup only database.

 

Thanks for your help.

do you use a seo module? like clean urls or something like that? You maybe will have to reinstall it. Or first try to empty cache.

 

But first check this: in advanced setting these options have to be set to No again :http://prntscr.com/eu3x0i   Its an image of dutch backoffice, but you will have to set the debug buttons to no.
