Owncloud 10.2.1 (stable) is working splendid on Ubuntu 18.04.1 lts…
I started to use the Diagnostics module for one user from my list.
The result in the owncloud.log:
“message”:“count(): Parameter must be an array or an object that implements Countable at /var/www/owncloud/apps/diagnostics/lib/DataSource.php#129”
Line 129 in DataSource.php: $totalDBParams += count($sqlParams);
Anyone can help?
