cannot save logo

I saw that “admin” posted on August 18th, 2017 that they cannot save or delete the logo in their Highend theme.

This is happening with me now.

I increased the memory, turned off any/all plugins, and it still keeps saying “saving now…” without doing anything.

You can see it on the picture: after I removed one of the logos, I tried to save the changes… nope, it’s just keeps going and going about saving now.

Help, I cannot edit the page:(
