Redirection not working

Hello.

After logging, the user is taken to the WP dashboard page. I’ve read any topic in this forum. I′ve follow every test and instruction, but for changing the theme. I am using Divi, and if your plugin does not work with Divi, I can’t use it. There are thousands of pages using Divi. I have no problem at all with paying to get support. What I want is to fix and issue which is bothering hundreds of users.

I appreciate de attention.

Best regards.
