Why is this closed without explanation or link to another thread? I have the exact same problem.

[kesselb]

Click on the link and figure it out?

[fthommen]

Your answer is not very helpful @kesselb. Forcing users to read through lengthy posts to find out why an issue has been closed is not very friendly. At least you could have posted the link to the related github issue (ONLYOFFICE/onlyoffice-nextcloud#21) or a direct link to your post with the explanation why you have closed the issue (https://help.nextcloud.com/t/documents-not-being-saved-when-editing-nextcloud-18-local-community-document-server-plugin/71382/29)

[fthommen]

@kesselb The closing comment of the Github issue that you are referring to (ONLYOFFICE/onlyoffice-nextcloud#21 (comment)) explicitely refers to the NextCloud team to solve the issue. Now both sides have closed their issues by pointing to the other party :-(. Please reopen this issue. Thanks

[kesselb]

At least you could ...

A friendly advice: Try to rephrase such sentences as questions. That sounds much nicer.

/71382/15 is a reference to a specific comment.

That comment to be precise. A link to the right issue on GitHub is included there. Actually you need two clicks to find the right issue. I don't see a problem here. Also the post at help.nextcloud.com includes more helpful information.

Please reopen this issue.

The right repository is https://github.com/nextcloud/documentserver_community and a issue is already filed over there. It's not necessary to open multiple issues for the same problem and it does not speed up things.
