Misstake upgrade

I did a misstake i think by the upgrade. So now seafile works but seahub is broken (web ui).
What would be best way to fix that issue?
Run it again e.g. from 6.0.8 to e.g. 6.1.3 and then to 6.1.4 pro edition?
How can i check isssu and what should i check? I try chom…
Other option i have a backup…6.08 but in the meantime there was some folderchanges. Would it work if i set back and will seafile know and sync delta (or can i do it manual…deltasync)?
Sorry I know a lot of questions.
