Bug after changing host and domain

[SachsCH]

Hello!

I have created a new online store on a test server which works without errors. Now I want to move it to the main server. I have done this according to the following instructions:

However, I have received the following error after the migration.
1) The product images cannot be displayed
2) If I logged signd in in the admin section there was came an errormessage of the module "welcome"
I was able to fix this problem by deactivating and reactivating the user friendly links and deleting the folder /modules/welcome.
Now almost everything works as usual.

However I now get an error when I disable the debug-mode. (No matter if you use the menu or the file like in the tutorial) All pages are no longer loaded and just appear white. When I check the log on the host I only see the error messages from before where the images were not found. For the new error I get no message.

I would be very grateful for any help!
If you prefer we can also meet on Discord, TeamSpeak or Zoom.

My data:
PestaShop version 1.7.6.8
Theme: ApCupid
PHP 7.1.33
MySQL server version: 5.7.26-log-cll-lve / web server cpsrvd 11.86.0.31

Check/regenerate .htacess and check the img folders permissions

It's ok to deactive, this module is useless, it's only the first-startup guide,

After server move you have to regenerate cache by deleting /var/cache (which should not have been moved actually). This should solve the issue
