Have cpanel, tried to upgrade from mysql 5.0.98 to 5.1.x using easyapache. After that happen my site went down and cpu went sky high with a ton of queries. Using php 4.4.9. Went ahead and downgraded mysql back to original version. Mysql back to old version and I can connect via phpmyadmin via whm but now my php scripts cant connect to mysql. Getting error:
Error establishing mySQL database connection. Correct user/password? Correct hostname? Database server running?
