Error Multistore PS8.1

[Krajsly]

Hello. In my panel, several sections (such as modules, payment settings, etc.) began to show the same error (in the attachment).
I assumed the problem was with the multi-store (I don't use it and didn't turn it on). But it turned out that when I try to enter the multi-store, I get an “access denied” message.
I am an administrator and have all access.
Therefore, I cannot find out if multi-store is enabled and how to fix the error.
It is not yet clear why he is in two places. I assume that some module is breaking this, but when I try to "disable modules" I get a huge number of errors and the store completely stops working.
At the same time, I did not install any modules, I just installed PrestaShop and updated all the modules that were there at the beginning.Can someone help me?

Hi, it seems that the problem is in the configuration module of the theme you are using, themeconfigurator. You can try disabling it to see if the problem is there.
I don't know if you have knowledge of the database, but another option would be to look at the ps_shop table to see if the multistore is enabled, if so, there you will find the different shops you have.
