When going back to this problem, the js error no longer appears in the console yet the problem persists, so I’m at a loss.
When clicking on your link above to open a ticket it takes me to a page that says I’m not authorized to open a ticket and directs me to log in, but when I go to do that it takes me to my WordPress.org profile page where I am currently logged in.
I have W3 Total Cache installed so I went in and disabled any minify settings then tried again with no change. I then deactivated the plugin entirely and tried again in a private browser window without change. Clearly there’s an issue, but I’m just not sure how to find it.
I tried the theme change as you suggested and that didn’t work. I pulled up the JS console and found an error (see screenshot at https://d.pr/i/ScO7fV), however, I’m completely at a loss as to how to weed out where the conflict might be. Any suggestions would be greatly appreciated!
