UPDATE: It works using Safari 12.1.1 (13607.2.6.1.2) and Tor 9.5 x64 (based on Mozilla Firefox 68.9.0esr) but there’s a NEW problem. The image is cropped incorrectly, using either of these browsers.

(For privacy, I avoid Chrome.)

OnlyOffice Document Server 0.1.7

This is not a version of ONLYOFFICE DocumentServer, this is version of Nextcloud's Community Document Server

Please note that Community Document Server was developed by Nextcloud Team, if you have any issues with it, please contact them in the appropriate GitHub repository.

If you are using our official method of integration (Nextcloud + dedicated Document Server instance as per our installation guide), we will be glad to answer your questions. Please see more info on our forum.
