I just got “Error Code: 404. Call Link seems to be wrong.” and couldn’t resolve the issue. I suggest trying another solution. ![](https://secure.gravatar.com/avatar/8bdc1820139ed2307c47e5a234e6f4b724ad2ecd55ace0752076510ac353c7a8? s=60&d=retro&r=g) ### 󠀁[My favorite calendar tool now has a killer WP plugin](https://wordpress.org/support/topic/my-favorite-calendar-tool-now-has-a-killer-wp-plugin/)󠁿 [Alex Medick](https://profiles.wordpress.org/alexmedick/) November 21, 2022 If you haven’t heard of Cal.com, they’re a killer open-source alternative to Calendly( cal.com is a much better product design and UX wise, imo). They just launched a WP plugin for easy integration on your WordPress site. It definitely rocks and you should be using this plugin + product right away.
