Today one of my sites has encountered an error in the css and js file. This only happens on one site, other sites on the same server function normally.
The affected site is https://adspop.me (screenshot)
When I activate development mode, which means that if I skip Cloudflare caching, the site loads normally. But when turning off the development mode the error occurs again.
I have tried to clear the cache several times and also custom cleaning on important css and js files, errors still occur.
