I just spent 3 hours debugging (aswell as a few other hours the last few days) a problem a buyer was having with my newsmail subscriber. It wasn’t sending emails from certain php files but was from others. And after all that debugging, do you know what I discovered it boiled down to… The BLOODY COLONS in the URLS that are displayed in the email… COLONS !? Come…ooooon…
What’s worse is I can’t replace the colons with “%3A” because percent signs stop emails from being sent too!!! Grrrrrrrrrrrrr this is the most fraustrating case I have ever come accross. This person is using godaddy, and my php app has worked with many other people who use this service… Just not this guy… Is he in an “annoy PHP developer” server or something? 
... * deep breath * 
Basically, has anyone got any ideas to solve the colon problem? I’m going to try a few different things, adding the colon with different charsets etc.
So anyway, purpose of this thread, what annoying debugging experiences or odd cases have you had? Or, have you got any ideas for a resolution to my problem
