The problem over here is that people don't read the thread. They just post "It doesn't work" and expect someone to post a solution.
But the solution is already in this thread!
Learn to read, folks!
This hack is working just fine. If there is something fishy going on it's most probably on your own server or vB install with all the hacks you have installed. There's a lot of folks that have installed xxx hack on the same hook and are wondering why it doesn't work. It's not this hack that is causing the problem. It's probably you.....

I installed it tonight on vb 4.1.3 and it ran before midnight and before the regular cron that updates the birthday at the bottom of the forum. I installed it about 10:30 CDT and about 11:30 I noticed the first post. It posted the persons birthday with the wrong date. If the before mentioned person whom posted could point me at which of the 18 pages to look at for the cure that would be nice. I am not saying it doesn't work I am just saying it's posting the birthday post on the wrong date.

I quit being lazy and found kras's fix on page 13. I am going to upload it and give it a try.

How do I insert a smilie in the message and message pl?

You must write the replacement text like this

Tried this already :happybday: which is the replacement text for an animated birthday gif. Waiting to let it run again. No one had a birthday in the last two days. I am waiting for it to run by itself without forcing it by adding a new user. :D

Works great now with three smilies. Fires off automatically after 12:00pm just like it's susposed to.

Is there a way to have the birthday greeting post in the users profile user message area rather then a specific forum?

I am pretty sure that I had installed the fix, but to be sure, I re installed it just now.

Got on, and noticed a new birthday thread. Check it out, and the guys birthday was 2 days ago on the 23rd!

Yeah, I installed the fix too and am still having issues.
