But the homepage is just a page generated like any other… I dont see other pages like for example the about us page to be like that /page/2 3 4 …. so why homepage… ?
The theme has no control over pagination and permalinks that is a core WP function.
And WP should not be generating pagination if you’re not on a paginated archive or page. So some other plugin / custom function is interfering with that. You would need to find which plugin/code is creating the issue.
I have blocked all plugins and theme functions is the same that came with the theme as default… other than css code to make the header sticky I added no other code.
As David mentioned, these things are completely handled by WordPress itself – meaning that you would get the exact same issue when using a twenty series default theme.
I would recommend checking with WordPress support team and see if they’ve seen similar issues before.
