Warcraftlogs Website not loading / loading partially

I am having an issue since yesterday evening with Warcraft logs website. It is very laggy, loading very slowly and never fully loads. Does not matter if I am trying to access the homepage or a certain log.

Adding two links to how it looks. There are some weird squares instead of normal icons. Never had an issue like this in YEARS of using logs, both the client and the website. Cleared cookies and cache on this site and tried using different browsers to no effect. Any help would be appreciated

I have the same problem when I try to look at logs in FireFox. Deactivating uBlock Origin doesn’t solve the problem. In Chrome the website works. Probably a bug introduced in the javascript-code.
