Hi,
Thanks for using our plugin.
The login form is not a template to edit. It is using the WordPress function wp_login_form();
However, we do not have filters to alter it directly.
The best way to add your own login form is to follow our themer’s guide:
https://theeventscalendar.com/knowledgebase/themers-guide/
To move and edit this file:
the-events-calendar-community-events\views\community\edit-event.php
Once in your theme you can wrap all the coding in your own logged in check and add your Login Form before ours shows. Then once someone is logged in using your form it would bypass ours.
That is the only method we have available to change how the form looks besides doing css.
Let me know if you have any follow up questions.
Thanks
