Hello, For me, your theme remains a mystery that I cannot understand. For a month I have been struggling to make the basic settings and I do not succeed. Today I found another problem along the lines mentioned in the previous messages. How is it possible for 2 users to log in to the same page / browser? I noticed that an Admin account and an Instructor account can be logged on the same internet browser. Cared that the correlation between Vibe BP, BoddyPress and Membership pro, does not work. Something is not ok. As mentioned in previous messages, the Instructor account has access to the Wordpress dashboard. Now you're going to ask me if I cleared the cash from the pages. THE ANSWER IS YES, I cleaned. Please access my admin account and check what is not working well on the theme installed on my site. I have been struggling for 1 month to make some settings and be able to open the site. I can't open my site because new problems always appear. If you don't help me with fixing all the problems, I give up the topic and ask for my money. Best regards
