After I upgraded to Wordpress, I noticed that the below error was displaying on the Dashboard:

Warning: preg_match_all() [function.preg-match-all]: Compilation failed:
this version of PCRE is not compiled with PCRE_UTF8 support at offset 0  ...

I did some searching, and came across this site where it gave me an idea of where to start looking. To resolve the issue, I upgraded PHP (for the heck of it) and upgraded Apache from 2.2.4 to 2.2.14.  Apache v2.2.14 has PCRE v6.6 built-in, whereas before the upgrade it was using v5.5ish which was causing the problem.  After doing this and making some adjustments to my httpd.conf file (I had to uncomment modules that I commented out) and restarting Apache, all was good.
