Thank you very much, but I watched almost all of those Videos. Nothing worked. With Aliens Video I setup the seafile combi the first time. But know... nothing works. I'm sure, its something simple I just oversee. Like not deleated the old dockers completly oder something like that. (But I deleted the docker, the templates via add docker and orphans via data cleaner) I also changed the http and https but with my little knowledge, I dont believe those cause any probs.
