Question css style are not working on forum sub pages and more problems

DB is okay!
Can I give you Joomla Backend access privately?

I can't promise anything,
it seems that upgrade left some bugs behind.
And you also use for the helix ulimate based template which also gives some problem sometimes.
But I'd like to see if I can find something in kunena .
But it would be a good idea to make sure you make a good backup of everything.
 

there is error messag
e when trying to create report:

the cause was multiple kunena_items in database with extra addition if one selects and deletes it it will create a configuration report.
and the unclickable kunena items and login may be due to main menu website overlapping the kunen's menu items "but this is still being tested"
but by this temporary code in the kunena Aurelia >custom.scss is he accessible Furthermore, a custom.css has also been created in the main site Template but this must be a user.css
so content of the custom.css transferred to user.css then adjustments colors etc also work well
