The other day my website suddenly started acting weird. When using the Flag module to flag content, i get a 200 error! The content does get flagged once i refresh the page, but when clicking the flag link i get this error below.
When editing any of my Views, and say i click on the THEME INFORMATION link to modify the theme files i get another 200 error (see image).
When trying to open modal forms, same thing. This problem seems to have come out of nowhere overnight, as my site was ok, i went to sleep, next day problems. Now, i get the error on both my own theme (when say flagging content) and also on the Admin theme (Seven) when say editing a View. So i would guess that its related to a module rather than the theme? Anyone have any idea how i can go about figuring out whats causing this? My JS is not good at all so im beat here, been on this for a few days now :(
Any help would be much much appreciated.
