Hello
Thank you for your advice but unfortunately solution does not not.

As I see the only difference is in line 42, 43: checking if Javascript mailto encryption is enabled. I had in that place previoulsy:
[$search = '<script src="' .WB_URL .'/modules/droplets/js/mdcr.js" type="text/javascript"></script>';]
so I think it was ok.
Anyway thank you
Regards
Grawi
