Meow Gallery Broken

Hello,
I have the free version of Meow Gallery on two websites and both were working fine until this weekend, now they are both broken. The problem seems to be intermittent, it appears sometimes but is ‘fixed’ after a refresh, and similarly appears on mobile devices but without any consistency. All was working fine until this weekend. Please see the pages of my sites:

I cannot guess if the problem will show for you but if you message me I can send you screengrabs.
Many thanks
Tim
