Modules Not Loading

[RubenBroadnax]

When creating course units the modules are not loading ... is there a fix for this issue?

[Mradmin-ops]

I have the Same question. In console I see: TypeError: this.$ is not a function which comes from coursepress-unitsbuilder.js:1459:11

Somewhere in this part:
fetchModules: function( unit_id, page ) {

It keeps loading the modules so saving or making changes to a course is impossible

driving me crazy as that never happened before! Tried de-activating all plugins, cache etc nothing works

Solution: Please don't update your WordPress version to the latest. The newest version does not recognize the $ even if you convert it with jQuery. You can downgrade your version to the older one, say 5.2.4 at least. You can install the WP Downgrade | Specific Core Version plugin and select a lower version. Make sure you have a backup of your site. Then re-install CoursePress Pro. It will surely work. The downside is that you cannot upgrade to the latest version.

Hi @Mradmin-ops ,

I was researching the problem you mentioned and came across this possible solution on WordPress' support forum which is :

https://wordpress.org/support/topic/problem-with-loading-modules-in-coursepress-modules-not-loading-and-stuck/

I'm new to web dev, so I'm feeling my way through and have not tried the proposed solution.
I hope it helps.

Proposed solution by daniduarte:

I went to check what changed with that in the update of WordPress to 5.3 and I saw the reference to this error “Uncaught TypeError: $ is not a function” in this post here: https://wordpress.org/support/topic/read-this-first-wordpress-5-3-master-list/#post-12124062

I searched about it and managed to solve (for now) my problem by changing the following file:

wp-content/plugins/coursepress/2.0/asset/js/coursepress-unitsbuilder.js

  in the line 1459, i change $ for jQuery, getting like this:
  this.jQuery(‘.unit-save-button’).removeClass( ‘disabled’ );

Find:
this.$(‘.unit-save-button’).removeClass( ‘disabled’ );

Replace it with:
this.jQuery(‘.unit-save-button’).removeClass( ‘disabled’ );
