I almost got screwed with the bootstrap.inc file. I was having an issue with the
warning: htmlspecialchars() expects parameter 1 to be string, array given in /home/opticist/public_html/includes/bootstrap.inc

I was searching all morning for a solution. What was happening was that my quicktabs weren't rendering properly. I kept getting boot strap errors in the last tab of my quicktabs. It was showing up in the actual page as well as the views admin section. 

Solution was found because i forgot that when I deleted the image gallery module extension. I forgot to actually dedlete the content that went along with that module. So in that content I had referenced a taxonomy term that wass trying to show up in the views but the module that went with that content was unistalled. That was the reason for the errors.
