Hi Nikola,
And thank you very much for your answer that really gave me the hint to solve our problem.
Issue was due to UseAnyFont Plugin, wich defined a font for all elements, that also applied to “.ui-datepicker a” in Calendar.
I just added Glyphicons Halflings to UseAnyFont and assigned it to “.ui-datepicker a”, works fine 🙂
Thanks again and congrats on your plugin and support,
Have a nice day,
