From version 11.0 Nintex form came with Hijri date. For Arabs it's great feature but for other languages that uses language packs it doesn't good!! I used Persian language pack. After upgrading to latest version of nintex form all of my date picker changed to Hijri date picker! and when I select Persian date from Site settings>Regional setting the issue is still exist!
Do you know any solutions for disabling Hijri date?!
