On my laptop installed English version of windows 8.1.
I installed libreoffice 126.96.36.199, then I installed the add-on running languagetool 2.9. The grammar checker for Russian language does not work. Then I read the documentation and have disabled:
* Lightproof grammar checker (Russian)
* Lightproof grammar checker (English)
However, the grammar checker only works for English. Spell check works for the Russian language and the English language. I made a screenshot of the Writer with the text and attached to this message. Please help in configuring.
