Hey guys,
Thanks to everyone for reporting the fact that the favorites section was broken. This has now been fixed! Sadly to fix it I had to wipe all the favorite courses ☹️ . I have now learned what caused this issue and will ensure this wont happen again.
For anyone interested, the issue was as follows. Yeshiva University changed some of the CRN's for courses so when my website re-scrapped the data, this overwrote many things which led to the course objects for user favorites pointing to nothing, hence the error. This was due to poor programming on my part, but this was a great learning experience.
Thank you all & have an easy fast!
