Is this a new "feature"? Since a couple days the entire base options section is just a link to buy premium, I can't change code position from header because it's all just a link to buy premium
You write that it started a few days ago? The plugin was last updated 2 months ago.
This means that there is a conflict with another plugin that was installed recently. Try disabling recent plugins to identify the culprit.
This is not true. Something is installed on your site that conflicts with the plugin. For example, the dark design of the admin panel or plugin or theme.
I can investigate the problem if you give me access to the admin panel in private messages here on the forum
I'm also able to reproduce on two different sites of mine the second I can't even access the menu whatsoever, on both chrome, firefox and a handful of derivatives
