Server configuration

Operating system: CentOS7

Web server:: apache(httpd)

Database: mysql5.7

PHP version: 7.2.24

ownCloud version: 10.3.0.4

Updated from an older ownCloud or fresh install: no

Where did you install ownCloud from:

Signing status (ownCloud 9.0 and above):

It seems an error related to the files_mediaviewer app. Make sure you are running a version of the app which is compatible with your 10.3.0 ownCloud version as well be sure the Gallery app is disabled as the two apps are proven to be incompatible.

I looks like a file error.
