Hello,
I have a conflict on the web with the translation mangement plugin and the theme. Before I updated and the site fell, I saw that this plugin was a problem and I left it activated with another theme and it worked. Until I had everything updated and it worked again with the subject. Now I have everything updated and I have tried to install several download plugins like download monitor or download manager and the site goes down. Until I disable the plugin wpml multilingual and wpml translate manager and the xstore core, I go to permanent links and save again and little by little reactive plugins and it works fine. I do not know why this error happens but I need to solve it,
