CSS import from Joomla

Hello guys,

First of all, i’m sorry if this is posted wrong or already exist. I’ve looked around the forum and googled for a while but i couldn’t find anything.

My question is, i think, really simple.

I have a website where i use Joomla. I want to change it to WordPress without changing anything of the website itself. For the import have i used Joomla FG to WordPress.
After the import i selected the child theme and realised that the html is complete but the stylesheet wasn’t included. The website is really simple and doesn’t contain much. i’ve played around with some setting but i didn’t find anything to solve it.
There are also a few searchbars that i don’t want.

I hope you can and want to help.

Kind regards,

Geert
