I don’t have the error message right now (I applied a quick fix), but I initially received a PHP error that xss_clean() function did not exist at line 212 in ext.safecracker.php.

I opened the file and noticed the xss_clean was not prepended by the global ee instance. I simply changed all instances of xss_clean() to $this->EE->security->xss_clean().

PHP errors when away.

However, my license key will not save now.

Good find, we’ll have that xss_clean bug fixed in the next release.

And ha, yes, the license number doesn’t seem to be saving. Well, I’ll fix that in the next release too. For now, don’t worry about it, it won’t have any effect.
