This is actually caused by an underlying problem with memory handling in MySQL. It goes through a couple layers of errors, of which only the outermost shows up on the site. I've just posted a temporary quick fix that suppresses one of the middle errors, so that it ought to be OK for a bit while I work on figuring out the full fix. Post again here if you are still seeing these layered exceptions (assuming you aren't getting them on this thread!) and include the link you saw it on. Thanks, Rachel

Ah, the girl with the spanners! It's working so far, I'll let you know if the duct tape slips.

Heres my grand conjecture: A typo while updating the template, say for different ads, or something of that nature, caused this problem in the center column. I know that because the left column will load multiple times, and the right only loads once. Also - the reason why it SOMETIMES works, is that due to a cache, it will occasionally use the older template, but after being viewed a few times, it updates itself. This is all theorizing.
Kiteman (author)  zachninme9 years ago
A-ha! More evidence for whoever is fixing stuff: I can't access my own thread directly, but when I click the link that came in the email alerting me to Zach's reply, here I am.
Kiteman (author)  Kiteman9 years ago
And when I posted that, I got a momentary "500" message.
I couldn't do it by following the email, but I just clicked for the heck of it, and it worked. And yeah, I got the error too... Is it fixed?
Dunno, I had it multiple times while at home, and now that I am not any longer, it hasn't happened. Still, even from home, normally a "try again" refresh (Flock or Fifefox browsers) would "fix" it.
Kiteman (author)  Goodhart9 years ago
Refresh wouldn't work last night. Today it's fine. Fixed, or healed, life is better.
Could I ask a question (if this is inappropriate, please let me know), but does the "kite" in your moniker refer to the raptor or to the paper and stick toy I flew when much younger (I had one that had over 3/4 of a mile of twine on it......I didn't know the danger of that at the time...but boy did it go high *lol* ), or maybe to the one drawn behind a boat?
Kiteman (author)  Goodhart9 years ago
It's the paper-and-string variety, in my latest Instructable, it's polystyrene and string. I used the name because my first major forays into online communities coincided with my first forays into kite-making, and I've used it ever since so that people would know me.
