error message

When I load my site https://www.bsatroop195.org/
I get a popup message that says “There is a problem with your theme. The file wppa.js is not loaded when it is expected (Errloc = wppa_kickoff).”
The error message indicates there is a problem with the theme. However I also get the following 8 error lines.
Please help.

Hi Lou! 👋
All these warnings are coming from a third party wp-photo-album-plus plugin, take a look at this screenshot too:

You can discuss it with the plugin development team, and they will help you with that.
The display_errors setting is turned off on production sites, but seem to have been left on, making the warnings visible on your site. To take care of it, please, add the following to your wp-config.php WordPress configuration file, replacing the line:
define(‘WP_DEBUG’, true/false);
with:
ini_set(‘display_errors’,’Off’);
ini_set(‘error_reporting’, E_ALL );
define(‘WP_DEBUG’, false);
define(‘WP_DEBUG_DISPLAY’, false);
Warning will not be shown anymore! ✅
Thank You I was wondering if it was the theme or the plugin. I am using both on other sites without the error also.
