Help with internal server error 500 in Payment Settings specifically on the verify identity screen.

I’m trying to sign up for partner payments… I clicked verify entity and then I keep getting a 500 internal server error… I keep updating but the error won’t go away. This has been going on for a month now. I have tried:

  1. Reload the page.

  2. Clear the browser cache and cookies.

  3. Visit the website using another network.

  4. Repair the database credentials.

  5. Check if there is a permissions error.

  6. I have used other browsers.

I have tried all the previous steps and none of them have worked. How could I contact support so they can help me? I have been receiving the same error 500 for a month now.
