Sidebar Course navigation not working

@tonk,

Please note that the link you shared is broken or does not work. As a result, we’ll need more information to further diagnose this issue you are having with either the Course Syllabus widget or the Course Outline widget on the sidebar.

I double checked that the Course Syllabus widget and the Course Outline widget are working fine. As a result, we need to do some troubleshooting to find out what is going on. In particular, we need to:

1. Rule out potential caching conflicts.
2. Rule out potential plugin conflicts.
3. Rule out potential theme conflicts.

Rule out potential caching conflicts.

To fix caching issues, please visit your website in?incognito mode?after each of the following steps.

• Deactivate all caching plugins you are using if you are using any. Purge or delete your plugin caches before deactivating them.
• Check if your website served by a content delivery network (CDN). If your CDN is Cloudflare, purge your CDN cache.
• Check if your website is using server-side caching. Your webhost can check this for you, and purge this for you.

Rule out potential theme conflicts

Please temporarily switch from your current theme to any other default theme on your WordPress site. Then, check your website again. If the problem disappears, then is some conflict with the theme. If there is a theme conflict, please update your current theme if there is an update available. If there there is no update available or the update does not fix the issue, you can also reach out to the support team of the conflicting theme.

Rule out potential plugin conflicts

If the issue persists after you switched to a default theme, please deactivate all plugins on your website except the LifterLMS core plugin. Check to see if the issue disappears. If the issue disappears, then there is a plugin conflict somewhere.

If there is a plugin conflict, reactivate each plugin?one at a time?until the problem re-appears. If you find the conflicting plugin, please update the plugin if there is an update available. If there there is no update available or the update does not fix the issue, you can also reach out to the support team of the conflicting plugin.

Hi Nick,
I checked the plugins and theme for possible conflicts.
I noticed that a Twitter widget (now X) was throwing errors. When I removed this widget everything worked as a charm.
So I can say that the problem was caused by Twitter widget in theme Bostan.
Problem solved!
