Randomized Questions on WPEngine Hosting

You can find the Randomize Order feature under Display and Content Options > Custom Question Ordering (or display subset of questions). This feature does not work properly with the default WP Engine settings. The following is needed for it to work properly:

Navigate to WP ENGINE > GENERAL SETTINGS
Look for ORDER_BY_RAND (which is set to “disabled” by default)
Change the setting to “enabled”

Once this is enabled, the Custom Question Ordering feature should work as expected.

Timing of Emails Sent by Notifications Add-On

To ensure the notifications function properly and emails are delivered on schedule, you’ll need to implement a custom cron job on your server. For the notifications to send properly and on time, you will need to add a custom cron job to your server. This is due to the limitations of WordPress’ mail system. See this article for instructions on how to set up a server cron job to help your notifications send on time.

Export Quiz To Excel Plugin by WP Plugins For You

Several reports have been raised about this 3rd party plugin causing quiz questions to be removed. If this has occurred on your site, please contact the plugin vendor for assistance in rectifying the issue.

SG Optimizer by SiteGround Hosting

The SG Optimizer (and other image optimizing plugins) can cause certificate images to be distorted, or contain solid black areas within the image. To mitigate this issue, it is recommended that image optimization be selectively disabled on images used in certificates.

Blank Settings Pages

This is the result of using LearnDash v3.x.x on any WordPress version prior to 5.0. To address this, upgrading to the latest version of WordPress is recommended. For users who don’t want to use the Gutenberg editor, you can still use the Classic Editor.

WPML and Quiz Question Answer Options

WPML translation capabilities cannot be applied to the available answers in a quiz question. This is being investigated further by development. There is no known workaround at this time.

“Duplicate Page” or Cloning Plugins and Quizzes

Quizzes and Questions should not be “cloned” with third-party plugins such as Duplicate Post. Doing so will result in irreversible issues. The cloned quizzes and questions cannot be used and should be deleted.

If you need to “clone” your quizzes, use the built-in quiz import/export feature found under LEARNDASH LMS > QUIZZES > ACTIONS > IMPORT/EXPORT. Alternatively, you can use a tool purpose-built for LearnDash such as WISDM Content Cloner. However, since this is only an alternative third-party solution please proceed with caution and always make a full site backup (database and files) before making any changes.

LearnDash support cannot assist with any issues resulting from using the Duplicate Post, WISDM Content Cloner, or other third-party plugins on quizzes or quiz questions.

Sorting or Matrix Sorting Questions Won’t Auto-scroll While Dragging the Answer to the Bottom of the Page

If you selected the Sorting or Matrix Sorting type of questions with items that are displayed outside of the screen area on the front-end, dragging the items down to the correct option will not move or auto-scroll the screen. You may have to instruct your students or users to scroll using the mouse wheel or zoom the screen view out so that they can drag the items to the correct answers. They can also press the arrow buttons or spacebar on the keyboard while dragging the answer to scroll the screen up or down.

If you are affected by this issue, you can try adding the following CSS to your site (Appearance > Customizer > Additional CSS) as we have found that it works for those having this issue.

.wpProQuiz_content .wpProQuiz_questionList,

.wpProQuiz_content .wpProQuiz_matrixSortString,

.wpProQuiz_content ul.wpProQuiz_maxtrixSortCriterion {

overflow: hidden;

}
