I just made a template based on what you wanted to make and everything is working. The only thing I did not do is setup this plugin and add their special coding to it. The idea is to make the page template you want and the loop you want (which is what I did), and don’t do anything special with it such as what the plugin requires. Test it and then proceed with the plugin. If you are encountering issues with the plugin setup for the template, this is where you will need to contact their support because it’s their plugin and instructions.
When you make your template, it’s important to copy the same code as the theme’s “page.php” file has, and save it in the “page-templates” folder. Also make sure that the top comment area has this:
/**
*
Template Name: Page Gigs
*
*/
Then make your “loop-gigs.php” file using the same code as the “loop-page.php” file has.
Test your new template, then proceed with whatever the plugin requires you to do.
