member.php HTTP Error 500 after upgrade 7.0.7 to 7.0.8

Upgraded from 7.0.7 to 7.0.8, now get HTTP Error 500 when trying to access account page.  Followed upgrade instructions to the letter.  Tried disabling all modules, resetting template to UNI.  Cleared cache, cleared browser cache etc. Replaced member.php with file from full 7.0.8 package.  Replaced .htaccess.  Eventually uploaded full 7.0.8 package to over-write all files and rebuilt permissions.  Still same error on member.php but rest of site works fine.  HELP!! 

Please can you check your web server error log for more information regarding the error ?

PHP Fatal error:  Call to undefined function Pmessages() in /var/www/inc/classes/BxDolPageView.php(607) : eval()'d code on line 1

Thanks Alex, I know what it is now, it was a modified function that's still there. I'll delete it then it should be ok.  Thanks, I should have checked the logs first.  That's why you get the big bucks!!
