There is a serious problem with the forum on my sites.
It is impossible to create a new thread and give an answer.
Naturally, I turned to the Kunena forum for support.

At the same time, I upgraded Purity 3 from 2.0.2 to 2.0.3.
But the forum does not work as on the template version 2.0.3 (ru.geschichte-chronologie.de ) , and on version 2.0.2. (de.geschichte-chronologie.de).
The test site jo.geschichte-chronologie.de is configured as ru.geschichte-chronologie.de.
The administrator of Kunena reported that the problem is related to Purity3.
"The problem arises because Purity III uses its own (perhaps modified) bootstrap.css. Rename this bootstrap.css in /templates/purity_iii/local/css/, then load the editor with Ctrl + F5 and everything should be there."
Firstly, I didn't understand what exactly I should do. Put bootstrap.css in the /templates/purity_iii/local/css/ folder? From where, delete there?
Secondly, maybe you will take some kind of system solution so that my site does not depend on self-made changes that will also have to be implemented in the future?
Thanks
