The error message is: Error saving the document.
I used synaptic to completely remove all installed LO packages. I deleted the hidden .cache files from/home/user. I re-installed LibreOffice. Problem is still there. Interestingly, I CAN save LO-Write files, but not LO-Draw files.
Suggestions what I can try next?
libreoffice --safe-mode
? Else need more info: Include the version i.e. runlibreoffice --version
in Terminal and see the output; Describe the file content i.e. ASCII/Unicode text, language font, drawing objects, etc (Edit your question to add these).
