When I try to install car attributes , from Delta theme' I get this: Error importSQL::ModelCars
cars_attributes/struct.sql How to solved it?

Try to check in your database if plugin tables does not exists already

I need to delete it from data base?

Yes installation will create new one

Ok thanks... I tried few times and get this "Error importSQL::ModelCars cars_attributes/basic_data.sql"

I have another general question for some reason in the control panel in the plugins window, I don’t see all the plugins to adjust/set up them for the project?, I probably bought a lot of them from you

You must first add all plugins.
For cars attribute issue, it will have some problem with your database and some queries are most probably failing. You will have problems to debug this and identify root cause.

"You must first add all plugins."

This is what I did from the beginning and I am reporting on this situation. For example I'm looking now Jobs attribute to set it up and see if it works at all and can't find it

Do you think the problem is with me? Because, strangely, but with Evo 4.4 I didn't have such a problem with it.

@Newbie
It's SQL error, not related to Osclass at all. Simply your database does not want to create structure proeprly.

And
And how to solve it?

You must identify what blocks you to install plugin. It's probably some part of SQL that your database does not like.
