I’ve just noticed that since the upgrade there is an extra menu in the footer. It is a standard one from the demo. It is not displayed on the mobile version.
I have tried deleting it but I can’t as it is not actually in the footer widgets.
Upon looking at the code, I’m seeing where the fourth section is just a blank div.
Could you please check your footer widgets to see if you have anything at all in there? Probably an empty text widget?
I was trying to access your site’s back end to check on it, and see if there’s possibly a malicious plugin, however, the credentials don’t seem to be working, could you check on that for me please?
And while you’re at it, please disable all your plugins and see if it starts working again just in case that’s an issue.
If it starts working again, just re-activate them one by one to see which plugin is the faulty one.
