I managed to install owncloud some years ago in a mysql db at an ISP for a former club of mine.
The other club members worked well with it. Now they experienced trouble ( they were automatically logged out 20s after successfully login into the web-interface).
So I decided to do the pre-work for an update to a newer version.
The Menu of my ISP allowed me to do a backup.dump, I did that.
And I changed the passwort for the database.
No I have trouble: the cloud itself is not accessible via the http-interface - error message :“Exception occurred while logging exception: Failed to connect to the database: An exception occured in driver: SQLSTATE[HY000]  Access denied for user …”
And I have only the dump of the db-tables. But not the user-created and stored files
The files are the most important
How can I access and download all the user files in the storage of the database?
With oc_share in phpMyAdmin I can see the files, and I can also identify the folder.
What kind of tool is needed to be able to backup them on my local computer?
Sorry for this newbie question -
