When I load the main page, there is a character encoding issue: Image

Interestingly, it appears normal when I open the link or when I log in.

Firefox also displays this warning on the development tools panel: "The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol."
