Check this other forum post…

that’s like way too much for me
I am not that advanced
I am thinking to do a backup for everything and initiate a re install of the whole ncp
it’ll probably be easier and i will have much less headache…

All you have to do is compare your config files to what is in that post… If you find it difficult then it might be better to start a fresh install…

yeah i see one difference at least but its a little overwhelming

@Pantelis can you remind me please where to find the nextcloud config file?
