Gallery App. problem with gallery.cnf

[Alexs_sm]

Hello.
I have OС 10.0.10 and Gallery 16.1.0
I’m in trouble. As soon as I add the gallery.cnf file to the folder with images, I cannot get into it through the gallery.
The file was created UTF8. Even an empty file, without settings leads to a problem with the display of images

Update
“message”:“Exception: {“Exception”:“Error”,“Message”:“Class ‘Symfony\Component\Yaml\Parser’ not found”,“Code”:0,“Trace”:”#0 /var/www/html/owncloud/apps/gallery/config/configparser.php(71): OCA\Gallery\Config\ConfigParser->parseConfig(Object(OC\Files\Node\Folder), ‘gallery.cnf’)

================================
I found the previous post with a similar error.
However, that the new version of the OC did not fix the problem.

Hey,

it looks to me that this was already discussed in the existing thread below:

Gallery App doesn't work any more

Hello, 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?
