Just in the last couple of days, I've had problems with some of the buttons on threads. On my home laptop, the quote button just sends me into a permanent loading sign (spinning clock). When I try to submit rep points or flag a post, I get error messages like "AJAX response unable to be parsed as valid JSON object"
On my work PC, the flag and rep points buttons just take me to the top of the page. Quotes work, but the format of the quoted section looks weird.
Oh, I've also been getting a wall of text on my posts. I have to type in stuff with < symbols and such to get spaces between lines.
