The issue you are facing: Nextcloud logging shows many, many PHP Errors related to opening or editing .docx or other Collabora-CORE elements.
Is this the first time you’ve seen this error? (Y/N): Not sure when this started. Recently Collabora documents were failing to open, but we’ve fixed that.
Steps to replicate it:
- Open or create a .docx file, or other Nextcloud Office task.
- Check logs, find errors.

I’ve searched google on this category of error, and the few hits I’ve found “open_basedir restriction in effect” all seem to concern short term bugs on version updates in the past. I’m not convinced that is the case here. ( See: https://github.com/nextcloud/server/issues/37921 )
Yesterday evening I was also finding a similar error, but referring to a different file:
Error is_executable(): open_basedir restriction in effect. File(/usr/bin/gpg) is not within the
allowed path(s):
I would like to find how to eliminate these errors, as they are flooding the log. Thanks for any help!
