Conflict with Rise Theme by ThriveThemes
Since LifterLMS 2.0.0, we’ve been transitioning to some more performant methods for various functions and interactions on the WordPress admin panel which rely on the Select2 Javascript Library.
We’ve recently determined that the Rise Theme by ThriveThemes also uses this library, but they’re loading an older version than we require and this causes some conflicts where LifterLMS doesn’t work when we’re using the library’s functions.
We’re working on a better solution to this issue for the long term but, currently, if you’re experiencing this conflict you can use the following code snippet to resolve the issue.
You can place this in a theme or child theme’s functions.php file or in a custom plugin.
