Error 500 after importing the theme

[petregeorgian]

Hello. I'm new to prestashop but this thing is just stupid.weired.

I installed prestashop, several times, and it works fine in the beginning. I did all kinds of settings and it works without any problem, BUT:

After just importing a theme that i bought (Eveprest pets), different items in the menu go straight to error 500. Even without trying to activate the theme. Just by importing it.

I tried different methods of importing the theme, from the pc, from the server, manual, just for the hell of it, and it does the same.

When copying the theme manually  in IMG, MODULES and THEMES folders it goes an extra lenght and doesn't access the admin side altogether and goes to error 500.

Can anybody tell me what to look at?

Thanks

in debug mode, when trying to access modules it says the following:

[selectshop.at]

The error is coming from jxblog. Disable this module as it is not native one. If you want to use it, please revert to the developer for to get support. If the blog module is part of your theme, ask for support of theme developer.

BTW I changed swear word you are using into proper vocabulary (your first post)
