I have a problem where my 'add new plugin' button doesn't work and it also doesn't appear on the normal menu.
I searched online and the solution that is being suggested is swap theme to check if the theme is conflicting or disabling some of the wp-core.
I have this site already in production and I would love to change it locally to another theme just for the sake of testing.
How can I do that? I try to avoid publishing a staging environment since it's a quite time consuming and I only need to debug this one problem.
Thanks in advance.
