After a normal upgrade via 1-click-upgrade from 1.7.8.2 to 1.7.8.4, modules of the shop are not working and showing only errors like [Semantical Error] ... "@AdminSecurity" ..., "@Template" ... etc.

[Abdurahman-Amat]

We performed a normal regulare upgrade by using the 1-Click-Upgrade module  from Prestashop 1.7.8.2 to 1.7.8.4  .  Then later when my colleague wated to check the orders, the errors were pupped up. It seems there are some misconfiguration, mismatch occured in the shop back office. Because the costumer was able to place a new order. At the moment the shop is in the maintance mode. 

 

Here are some othe screen shots of that errors 

When a order or a customer of the order is clicked, 

when the store Bills / Invoices are clicked , 

Or other modules are clicked ,

 

Maybe some of you can have an idea, where the problem is rooted.

 

Any help and advices are highly appreciated!
