Finally after two years of contemplating the updates to Apache 2.x, MySQL 5.x, and PHP 5.x, I finally updated my server to the latest version os Apache, MySQL, and PHP. I was not too concerned about custom work or any of my WordPress sites, but I was concerned XOOPS and/or XOOPS modules would have some problems, but it is now a week later and everything is running smoothly. Why finally? Well, as of the end of this month, support for PHP 4 will be discontinued. Better late than never. Time to update your servers too?
