I combined my theme with the twenty twelve theme and found out that the error is in the functions.php file. It was because I added the snippet “remove private from post title” I fount on CSS tricks
@mercime I made my own theme. I also tried using the page.php from the twentytwelve theme but that didn’t work either even though if I activate the twentytwelve theme everything is fine.
Because the title of the profile page (and create group page) is the whole link: <a href="url.com/profile/...">Settings</a>
Maybe someone could tell me what I could change in this title script.
@mercime Thank you for the hint. The twenty twelve theme displays it correctly, I will look at my them more closely. If I find the mistake I will post it in case someone else has this problem too.
It shows up in both in the Profile page and the create group page, there is the title with the link and then sometime the title without the link. I am using my own theme, I guess thats also the reason for this problem. What could I change in my theme to remove this? Or which file do I have to edit?
