xss filtering Q: Fatal error: Call to undefined function get_instance() ...system/libraries/Input.php on line 855

It is important to filter certain data for XSS, but this is not in itself a reason to check all data for XSS by default - it should be your choice as the developer to turn this on or not. Similar I suppose to the magic_quotes setting in php, it's usually always on by default, and that's annoying.

As for the error, I don't know. I use FCK editor for my CI CMS but I haven't upgraded yet.

If get_instance isn't defined, then no controller has been called yet which is strange. I haven't downloaded the new CI yet so can't really help you further, the Input lib has changed in the new version.
