Configuration file, /.../cgi-bin/links/admin/defs/database.def, is not readable.
I tried 0644, 0666, 0755, and, 0777 permissions on the file, but no change. (It's been so long since I installed it, I can't remember if there's anywhere that says what to manually set permissions to. The manual I have doesn't seem to mention anything.)
I did find this thread:
But resyncing the Category properties has no effect on the database.def file. Is there any way to get at that one with a resync?
All the database connectivity appears to be fine in the admin panel...
