WordPress bloggers must check PHP, MySQL versions of their hosting server.
Most hosting providers and personal installations on Unix/Linux systems should be able to host WordPress under very common configurations. However, WordPress server requirements for different Version may changes depend of wordpress upgraded features and plugins supports .. etc
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.
I 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.
