spellcheck stops working suddenly

I’ve been using LibreOffice since about 3.9 and built a library of macros and specialized dictionaries. Between shut-down last night and booting today the spell check stopped working. No squiggles and running it explicitly says there are no error. This has happened multiple times, and prompted my transfer to LibreOffice from Open, but still happens.

Fixes on here involve deleting everything in a profile or other fixes that assume the problem is from a fresh install. I don’t want to have to rebuild my macros and dictionary. How can I fix it, and preferably prevent this happening for again?

I think you meant “3.0” rather than “3.9”. Which version are you currently running, and under which operating system? Are you using the default file format (ODT) or some other format? Which language dictionary are you using?
