I would be forever gratefull if you could help me with this problem (i've been trying to solve it for weeks now).
On my site I use polylang to create a multilingual site. Everything works fine, except I can't publish posts in a normal way - when I write a post, click publish and then try to view it it shows a 500 server error warning. If I then delete the post and restore it from trash it works fine. Does anybody have any idea what to do?
I know it's the polylang's fault because I've tried elliminating all plugins and only polylang causes this problem.
I'm using Wordpress 3.9.2 and polylang 1.5.4 with theme Responsive.
Thanks for all your help!
