Setup back my Login from CUSTOM to Wix-ORIGINAL

The deeper i dive the more issues i do find…

Now i am facing the same LOGIN-ISSUE like described in this post…

Since i could not find a solution, i have had to LOAD and older RESTORE-CHECKPOINT from the HISTORY.

This way i got back the original Wix-Login —> But now it is not working at all…

Anyone capable to check this?
