Ok. All the members are actived, none were added manually. So like I told you, I can see all the members when I go to https://puentealarte.com/nuestros-artistas/. The problem is only with the search page, , look at my last screenshot, please.
I deactivated the plugin “Paid Membership Pro” for test your approach, but it didn’t working. For the moment, I don’t need to use this plugin, but I will on the near future.
