Hi Chirui,
I’m having the same exact problem. Did you ever get this resolved?
I have been getting this error too, but only in the WordPress dashboard. My site itself is refusing to load and visitors are greeted with an internal server error message. I have had to deactivate Relevanssi as a result. Any solutions?
I just wanted to post an update for anyone else in the future who might run into the same problem. The issue was with the functions.php file — there was a missing curly bracket at the end of the file and while it did not cause problems anywhere else, it was preventing my theme from autosaving.
Thanks for anyone who took a look.
P.S. — The site in question is http://www.geekinheels.com if you need to take a look at the source code.
