MaximenuCK doesn't display correctly and work

Hello,
The site was moved to a new webhost after it fell victim to hacker attacks which may have contributed to the problem, and only the domain name was moved, no files, but how can this affect the plugin behavior?
Could you please give me any hints as to how should i proceed to solve the issue?

the fact is that your website is blacklisted, so the browser blocks the content coming from it.
you have to check the advices from google
developers.google.com/safe-browsing/v4/advisory

I can not do anything by my side ...

Ok, I managed to solve the problem by removing the Firefox profile from AppData/Local/Mozilla/Firefox/Profiles folder and it worked. I will set the website up accordingly so google can reevaluate its state and remove it from dangerous website list. Thank you for the help Ced
