 * Hi,
    I’ve just upgraded my blog to the new 2.1 and everything seemed to be working
   and running smoothly until I tried to write a new post.
 * As soon as I try to save the post I get a error message saying “Stack overflow
   at line: 500”.
    I’m running Tarski theme.

 * Anyone know how to resolve this?
 * / Mikael

 * Nevermind this one, resolved it myself.
 * Error was caused by two editions of prototype.js being loaded, one by WP Core
   and one by Tarski theme.
    Commenting out the linein Tarski fixed everything.

 * In what file do most themes call prototype.js?
