[Gelöst] Redirection Issue when Sub-Folder Installation is enabled

We have an issue on our site versteckter Link where we try to access blog category , but instead of routing correctly it goes through multiple permanent redirect hoops (301) and then ends up on 404 page. The issue here is that the category exists and it worked before.
What was changed today - we went live with our changes and changed the domain URL from investor.wptest.bondora.com to bondora.com
