Error on Page

[kmspt]

Hi! I just took over the wordpress from a prior developer who left and when I go to a page that was created, I see the following error:

Uncaught TypeError:JQuery(..)mask is not a function on line #4 in website/contact-us/&ct_builder=true&ct_inner=true&oxygen_iframe=true

@kmspt I expect that error to be caused by a conflict with another plugin on your site. Please run a plugin conflict test to determine if that's the case: https://pluginconflict.com/?plugin=Oxygen.
