Thank you for this reply! I’m not understanding your instructions on how to add spell check to the onlyoffice documentserver App in Nextcloud? I’m also not seeing the same location of files that you are? I’ve installed document server on my Nextcloud and my location of document server would be in my apps folder of Nextcloud:
I’ve searched and I can see “SpellChekcer” referenced in Help and Images folders only.
Also, is it that you are removing (renaming) the node_modules and after updating the document server app will download a new version of node_modules? Is this what adds Spell check to the App documentserver?
