Overview fixes

Description

Previously pagination did not show up unless a user was looking to the puzzles on their own profiles or if the user was an admin. Now the pagination always shows up like it should be. Furthermore, I found another issue that users could press the button for show solutions on their own profile, but that this button did not actually show the solutions. I fixed this issue as well.
