[Tutorial] Spell Check Not Working (words red underlined)

[Hagar Delest]

It is the most frequent question in this forum!

There are already tutorials for that. The easiest fix is to reset the configuration. Follow the steps described here: resetting your OpenOffice user profile.
Note: reinstalling won't change anything if the profile is not deleted, which is not done automatically when removing the application.

A script has been developed, it may help you fix it automatically without resetting the whole profile: Spell checker "red wriggly lines" - beta test fix for AOO.

If no change, then follow this topic: [Troubleshooting] Spell check in OpenOffice.
