Hi @stevefwdedu,

I was able to replicate the same issue in an test environment. As a result, I have informed our developers about this so that they can file a bug report. Just please note that for bugs and feature requests, we cannot provide an estimated timeline of when they will be fixed.

As a workaround, you can just install the free Advanced Custom Fields plugin from wordpress.org/plugins/advanced-custom-fields so that you can create a course excerpt text area in the block editor (Gutenberg). This will allow you to save manual course excerpts.

Hi @tinacornish,

Since this only affects one and only one course page on your site, we need to check if there are any error being logged. This error logs will give us a clue as to what is going on. Please follow the steps in lifterlms.com/docs/how-to-debug-a-white-screen/#log to enable debug logging in your site (if it is not yet already enabled). Then, to check if debug logging is indeed enabled, please visit /wp-admin/admin.php?page=llms-status and make sure that and Debug Mode: says Yes and Debug Log: says Yes.

With debug logging on, please try to make the changes again on the problematic course. Try to do this multiple times, just to be sure something will be logged. When making this changes, also make sure that the JavaScript console is open. If you seen any errors in the JavaScript console when trying to save the change that would not save, please take a screenshot of the JavaScript console and send it to us.

Then navigate to /wp-admin/admin.php?page=llms-status&tab=logs and view the debug logs. You can use Ctrl + F keyboard command to search for error or fatal error that is logged on the current date. You may copy that error message and send that to us.

Hi @yourbudweiser,

You can try using the llms_certificate_sequential_id_format filter from wp-content\plugins\lifterlms\includes\models\model.llms.user.certificate.php. I have not tested this but, after inspecting the source code of that file, it appears that you can try returning the array below to remove the zero left padding.

array( 
 'length'    => 6,
 'character' => ' ',
 'type' => STR_PAD_LEFT
)

Another filter you can use is llms_certificate_sequential_id. That filter is also located on the same file. We recommend that you review that file at wp-content\plugins\lifterlms\includes\models\model.llms.user.certificate.php so you can decide on the best solution for you.

Hi @andrusito,

I have consulted our lead developer about this. This database error is not specific to LifterLMS. WordPress users generally experience this WordPress database error Commands out of sync; you can’t run this command now for query error, even for those who are not using LifterLMS.

Nevertheless, we can do some troubleshooting to identify what is causing this. Could you try to check if this issue will disappear if you rule out caching issues, rule out theme conflicts, and rule out plugin conflicts.

• To rule out caching issues, try to disable any caching plugins that you have and see if it stops future errors like that from being logged.
• To rule out theme conflicts, kindly follow the steps in lifterlms.com/docs/troubleshooting-with-lifterlms/#theme-compatibility.
• To rule out plugin conflicts, kindly follow the steps in lifterlms.com/docs/troubleshooting-with-lifterlms/#disable-plugins.

You may also need to check if there are memory-related errors in you logs, since those memory-related errors can potentially be a reason for that database error.

Hi @creativenorthmedia,

Lessons can already be cloned into multiple courses: the only catch is that this action will automatically clone the lesson. That cloned version have the exact same content as the original lesson — the only difference is that it will have its own post ID since it will be a separate post altogether. You can learn about that in lifterlms.com/docs/using-course-builder/#how-to-clone-lessons.

If you are interested in attaching the same lesson to multiple courses without cloning the lessons, the potential side effect is that you will also have to ensure that any progress made towards that lesson will not be counted as progress towards all other courses associated with that course. If this is okay with you, then you can start with the add_existing_lesson() function of the Backbone.js code from lifterlms/assets/js/builder/Views/Elements.js and from lifterlms/assets/js/builder/Models/Course.js, and then work backwards from there. You can see that code from our GitHub repository.

Hi @imranmalix,

Currently, we don’t have a “My Grades” shortcode as you can see in lifterlms.com/docs/shortcodes. As a workaround, you can create you own shortcode whose output is based on the file at wp-content/plugins/lifterlms/templates/myaccount/my-grades.php. The variables that are used inside that file are defined inside the lifterlms_template_student_dashboard_my_grades() function in wp-content/plugins/lifterlms/includes/functions/llms.functions.templates.dashboard.php

Hi @sokym,

In this case, you need to make sure that the quiz is published. Unpublished quizzes will not be shown to students, but it will be visible to the WordPress administrator.

Once you publish the quiz, the next thing you need to make sure is that the students taking the course are enrolled on the course. Otherwise, if the students are not enrolled on the course and are only seeing the lesson if it is a free lesson, then these students will not be able to take the quiz. To allow your students to enroll on the course, you need to add an access plan as shown in lifterlms.com/docs/what-is-an-access-plan.

@thriveher,

We did update the user interface for the course builder documented at lifterlms.com/docs/using-course-builder. We have yet do update the documentation and any videos we have regarding the course builder.

Could you let us know specifically what you are not able to do inside the course builder? Based on the screenshot you sent, it appears that you were able to create 2 sections with the second section having 3 lessons. Note that once a lesson is published (and once you confirm that the changes are saved), you need to refresh the page (i.e., reload the course builder page). Once you do that, you will then see the Permalink to the lesson you created.
