WordPress Bloggers must find the PHP version and MySQL version of their hosting server now. The WordPress minimum requirements have changed and if your hosting server PHP and MySQL version is outdated, upon upgrade to WordPress 3.2, your site may not work.
PHP, MySQL Versions in WordPress
The minimum requirements for WordPress 3.1 (current version) are PHP 4.3 and MySQL 4.1.2. But the The minimum requirements for WordPress 3.2 (which is coming very soon) is PHP 5.2.4 and MySQL 5.0. So though most web hosting services would have updated their server, you need to be sure and not get stuck during update.
The easiest way is to install the Health Check Plugin – Its a simple WordPress plugin which will check checks PHP and MySQL versions of your server and compare them with WordPress 3.2 requirements.
We installed it and got an this response.
The response suggests excellent – we are running on PHP 5.2.16 which better than required 5.2.4.
I suggest you also check your PHP and MySQL version and contact your webhosting if your server falls short. Of course, if your hosting provider cannot upgrade your PHP and MySQL, its time to find a new web hosting for your WordPress blog.
