Problems saving and translation not showing

Hi guys!

My site: https://www.lchfarkivet.se i showing most of the translations I have made using this plugin, but lately when I add some translations i run into two problems.

1. When saving, it seems to be something wrong when I press save. I do think the translations are saved, but when I try to navigate somewhere else I get a prompt saying that if I leave now all my changes will be lost.

2. The translations that I have made lately since the above problem has occured just won’t show up on my site although if I go to the language file after and check, the translations I have made are saved.

Really need som help here.
