after the last update of the gallery app (-> Version 16.1.0) the following error appears in the logfile:
“Class ‘Symfony\Component\Yaml\Parser’ not found at /var/www/html/owncloud/apps/gallery/config/configparser.php#94”
The error is caused by the missing folder ‘vendor’ in the correspondig app-folder of the gallery app - in other words, the symfony components could not be found.
I tried to copy the ‘vendor’ folder from a backup but that doens’t solve the problem.
What can I do?
