most of the sources after discudemy aren't working

[dakar111]

After discudemy almost all the other websites get passed through and have no results/aren't working properly(you just see the total course number on every line) ; then the script just closes.

My suggestion:

Keep: discudemy
Add: https://yofreesamples.com/courses/free-discounted-udemy-courses-list/
Remove all the rest.

The above 2 websites together will rarely miss any coupon.

You can remove websites your self which u don't like by simply editing bunch of lines in code
