|Thats... not very helpful as a bug report. |
Considering what I and many other developers do - that is provide code to the community for free in our spare time to help others develop their own skills, some kind of effort at bug reporting is always helpful. Its like a man to mechanic: Says nothing. Passes keys to a car with a some form of fault. walks off.
Line 147 looks to be a blank line. However, I noticed an issue and the code will be updated shortly.
If you do have any more problems, please can you provide a bit more information - investigation will help you understand how things work.
print_r() or var_dump() are your friend.
