Support
2

To be honest I never installed IP in a subdirectory.

  1. Pls Post your .htaccess (you can censor the the Domain)
  2. Also did your environment statisfy this REQIUREMENTS?
  3. Did you change the IP_URL in the ipconfig.php to https://domain.tld/subdirectory ?
  4. does the required use have all the rights he needs?
  5. What ServerOS are you running on?
  6. Which PHP version is getting used?
