I strongly doubt this has anything to do with the actual website, the "MYLOGO" string is used when the browser for some reason can't load the actual logo picture and in the first screenshot it seems like the browser hasn't loaded the css properly. Try with another browser or try to reload the page whilst overriding the cache by pressing Ctrl + F5.
Otherwise it's most likely an issue with your network. Try accessing the forums with a different computer or a phone on the same network and on a different network see if it's any different. (Home and work networks for example.)
