I use Owncloud v.10.02 for several months, installed on my web host (in a subdomain), with Softaculous apps installer.
For a few weeks I noticed that on the server, the total volume was increasing and I realized that even if my Owncloud contained only 40 GB of files, when I went to see in the CPanel with the file manager, the directory ownclouddata exceeded more than 382 GB.
Suspecting that it was a problem with the contents of some “files_trashbin” directories, I tried to read a little about it, but I thought it was probably time to update my owncloud to version 10.0.8.
Tonight I made an update (with Softaculous) to Owncloud 10.0.8
So here I am with the update installed and when I go on the web server, I have the following messages that is required actions:
I’m going to spend hours of fun to find ways to make these corrections in my config.php ???
And my ownclouddata dir still exceeded more than 382 GB ??? Why…
