Niedzviedz, you changed the english version manual to polish. We now reverted it back to English. You can find your edits in the history of the page. Please, ensure that you only change to polish pages ending with /pl, or redirect those to pages starting with Pl: See eg the Dutch (Nl) version of the manual.
Hi, 3.0 manual has been blocked. All new edits should happen on the 3.1 manual. 3.1 Manual has been created starting from the last version of the 3.0 manual, see User manual
