If your Jones & Bartlett EMT or AEMT course is not loading correctly, or if a knowledge check, quiz, or activity is missing, use the steps below before contacting support.
Common signs of a loading issue
You may be having a browser or device issue if:
a knowledge check does not appear
an activity will not load
part of the lesson is missing
a page freezes or stops moving forward
buttons or interactive content do not work
Why this happens
Most of the time, this is caused by a browser or device issue, not the course itself. Common causes include:
outdated device software
outdated browser software
stored browser cookies or cache
browser extensions or plug-ins interfering with course content
Some extensions, especially Grammarly, can interrupt how JBL course content loads. Extensions add extra code to webpages. That extra code can interfere with interactive content and may prevent knowledge checks or activities from appearing correctly.
Step 1: Update Your Device and Browser
Make sure your computer, tablet, or phone is fully updated before using the course.
Please check:
your device operating system
your internet browser
any pending software updates
Using the latest version helps the JBL course load correctly.
Step 2: Clear Your Browser History and Cookies
Old browser data can prevent pages from loading the right way.
In Google Chrome
Open Chrome.
Click the three dots in the top right corner.
Click History.
Click Clear browsing data.
Set the time range to All time.
Check Cookies and other site data.
Check Cached images and files.
Click Clear data.
After this, fully close Chrome and reopen it.
Step 3: Restart Your Device
Restart your computer or device after clearing your browser data.
This helps:
refresh system settings
close background programs
clear temporary issues that may affect course performance
Once your device restarts, log back into the NAR LMS and try the course again.
Step 4: Turn Off Browser Extensions or Plug-Ins
Browser extensions can block or interrupt JBL course content.
This is especially common with:
Grammarly
ad blockers
password managers
privacy extensions
writing tools
Important
If you use Grammarly, turn it off before opening your JBL course. Grammarly can interfere with interactive lesson content and may prevent knowledge checks or activities from loading all the way.
Step 5: Use Chrome Incognito Mode
If you are not sure which extension is causing the issue, open the NAR LMS in Incognito Mode.
Incognito Mode is helpful because most extensions do not run there.
How to open Incognito Mode in Chrome
Open Chrome.
Click the three dots in the top right corner.
Click New Incognito Window.
A new dark browser window will open.
Log into the NAR LMS in that window.
Open your JBL EMT or AEMT course again.
If the course works in Incognito Mode, a browser extension is likely the cause.
Step 6: Return to the Course and Test the Activity Again
After completing the steps above:
Log back into the NAR LMS.
Open your JBL course.
Return to the lesson or activity.
Check whether the missing knowledge check or activity now appears.

Support Reminder
Many JBL course issues are caused by browser extensions, especially Grammarly. If part of your course is missing, this should be one of the first things you check.
If you want, I can also format this into a cleaner Moodle HTML block that you can copy and paste directly into your LMS.
