Unable to change jersey

[Radunion]

When I upload a jersey design, everything seems to work; I get the green "jersey saved" message, but the team jersey does not change. I tried a file that worked before, so this should not be the problem.

When I try to go back to a single color jersey, I get "Error Code: 0 Error Message: Request method POST (operation changeJersey) not supported for team".

Also tested it to change it to a custom jersey which doesn work, it says

Technical Error

It worked at some point, but I have no idea why? Maybe it was connected to another bug that was solved. In sprint some teams' saw the new jersey earlier than me, so the old one is probably cached somewhere.
