Hi @AramBakir. This does not sound like something is wrong in the code base (a so-called "software bug"), but instead like a support request (how to change settings, questions how to do something, etc.).

As Wikimedia Phabricator/Maniphest is for bug reports and enhancement requests, please ask on https://www.mediawiki.org/wiki/Project:Support_desk or https://discourse-mediawiki.wmflabs.org/ with way clearer information what you want to do.

Thanks for your understanding!
