Help! I can't move forward as the code challenge keeps hanging!
There appears to be a bug with the coding challenges in this course.
Customising Django Templates – Part 2: Building Custom Tags – Step 6: Create an Inclusion Tag (Coding Challenge)
When I enter the code on this challenge and press "Check work" the browser hangs and then I get this error message "Oh no! We didn't hear from the challenge service in a timely fashion." (attached below).
It's very frustrating as I know how to complete the coding challenge, but am prevented from signing off that course.
Could it be my browser? Do you recommend a particular browser setup to complete these challenges?

Your attachment doesn't seem to be present, but just in general, when the system does not "hear from the challenge service in a timely fashion", it is likely that the code contains a loop that never ends. Look for typos in conditions or other reasons a test condition might never change state, or unintended recursion (a function or method calling itself).
If that hint doesn't help you find it, show your code (preferably with a snapshot link) and provide a link to the challenge page to make it possible to replicate the issue.
