Data is good. To make sure, I change both folder and config to data. No change.

metadata.db is in the right folder (/data).

Always the same error on Cops Configuration Check (error 1).

Edit : Ok it's working ! After some desperation time, turn out it was a *simple* php permission problem. The data folder was a copy from a personal directory on the NAS, with herited permissions. I can sleep now :-) Thanks for the help !
