Correction can't detect any errors

EDIT : tools → language → whole selection seems to be not selected on my language, that explains clicking on auto-correct or manual correction was not working. Looking in settings and reinstalling were unusefull. I discovered Grammelecte (french) by the way

Correction doesn’t underline errors, either auto nor manual mode.
Basic dictionnaries installed + Grammalecte (I’m a french language user).
In corrector manual box, no language is selected, I select one, relaunch and still no results and no language selected.
In linguistic settings, all is set.
Attempted to solve :

  1. upgrade from v. 5.0 to v. 5.1.
  2. Uninstalled → reinstalled.
  3. Google gives me only results on this problem about OpenOffice or MS Office.
  4. I think about using Google Drive or an online writer. -_-’

What language is your paragraph style set to?

I don’t get it, seems to work correctly and stay after just click on wanted language in tools → language → whole selection. my language in whole paragraph and whole texte is not clicked.
Manual and auto corrector seems to work after 2 times reboot my document. Thanks for help !

Go to Tools / Options / Language Settings and make sure your Default Language for Documents is set correctly. Then go to “edit Paragraph style” and make sure your language is set under the Font tab. That should do it.
