Gravity Forms [Tested in version 2.2.5, but this issue can exist in other versions of Gravity Forms]

Fixed conflict since update of Booking Calendar 8.1.1

Conflict paid versions of Booking Calendar with "Gravity Forms" plugin, if in "Gravity Forms" plugin was used "masked input" field(s).
Because of this conflict is generating JavaScript error and as reason of this, Gravity form is not showing and also calendar in Booking Calendar is not showing, as well.
Since update 8.1.1, Booking Calendar will not load masked input script for times fields, if was loaded masked input script in Gravity form. Its means that masked input for start/end times text fields, will be used as standard text inputs.

If you are using older versions of Booking Calendar, you can make this fix to resolve this issue.
Please open this file ../{Booking Calendar Folder}/inc/_ps/personal.php
( you can check how to edit files in WordPress menu in this article )

and replace it to this code (comment that line):
// wp_enqueue_script( 'wpbc-meio-mask', WPBC_PLUGIN_URL . '/inc/js/jquery.meio.mask.min'.((WP_BK_MIN)?'.min':'').'.js', array( 'wpbc-global-vars' ), '1.0');
