I received these two error messages today. Not sure where they came from or what I did to cause it. Any suggestions on how I fix the problem and what caused it?
1 - warning: htmlspecialchars(): Invalid multibyte sequence in argument in /home1/XXX/public_html/includes/bootstrap.inc on line 856. 2 - user warning: in /home1/XXX/public_html/includes/cache.inc on line 108.
