Pagnation 404

Hi there i have a problem with pagnation on my website.

As it looks like there is a permalink problem. If i click on “next page” i recieve a 404 error due to wrong Link.
So it looks like category/2/page/2 but should look like /page/2. If i hover over the “next page” button i see the link category/2/.

Hope someone can help me.
I have few plugins installed:
Rank Math, Elementor, Cache enabler and Asset Cleanup.

On Settings/Permalink i have set to “Postname”
