Mobile menu not loading/can't edit styles

Hello - I'm having an issue with MobileMenuCK on thompsonmemorial.net. I attempted to edit the style of the menu but received a "failed" pop-up (see attachment 1) when adjusting any settings and also when trying to save. The changes do not save and now the mobile menu doesn't appear. The site moves down and the background of the menu appears, but the menu toggle is missing and clicking has no effect (see attachment 2 - the red rectangle is where the menu should be). I've switched to a different template to test and the issue persists. Any help would be appreciated, thanks in advance!

Hi - I mentioned it above, but it's thompsonmemorial.net/ . And I've emailed admin access. Thanks!

the front problem is related to the style
for now you can disable the style (remove the style selection from the mobile options of the module) to let the default appearance
