Hi, after many attempts i figured out that PolyLang is incompatibile with EasyReservation or viceversa!
The previous versions of both plugins were working well together, but now with the new versions these result incompatible.
I have notified via email the author of EasyReservation.
The problem is that when i activate polylang i wont be able to see and edit my resources in EasyReservation. If i deactivate polylang everything turns working fine.
Any help would be apreciated.
Thanks for all the good work.
