page not found when i try to blog

OKAY THIS IS THE THIRD TIME TODAY I'M GONNA TRY TO POST THIS BC WHENEVER I TRY TO BLOG AND THEN PUBLISH IT LIKE NORMALLY I GET 'PAGE NOT FOUND' AND THE DAMN NYAN CAT GIF EVERY SINGLE TIME. MY COMMENTS HAVE BEEN LIKE HELL FOR DAYS TOO MY COMMENTS DON'T UPLOAD AT ALL AND WHEN I CAME BACK TODAY (it's been 4 days) THAT SAME COMMENT HAD BEEN POSTED LIKE 20 TIMES. If the person I replied to recieved a notification for very single one of those I am so sorry this is embarrasing... I wanted to put the screenshot of it in here butmaybe that's why my blogs don't upload so let me try without now.
