Hello everyone, I have a problem with the forum, the themes with their titles, the comments of them and the private messages appears all empty. This problem began today with 2.0.15 version, then it was updated to 2.0.16 and 2.0.17 version and the problem persist. I put 3 captures that shows the problem
