After installing the plugin everything worked fine. Today, the calendar page has been redirected to suspicious pages! I do not recommend the plugin. Waste!
Activate you plugin, my page new redirect on:
https://newsredir.com/?p=gm2wcmrxha5gi3bpgeytm&sub1=Ilul&sub2=syst.v2#
WTF?
Yet the site worked well and without any intervention it started redirecting.
I use a powerful WordPress password, I’ve updated everything.
It does it only when I turn on the plugin, otherwise it doesn’t happen.
So redirecting to some dubious sites is happening only after you activate your plugin for reservation.
