 * My web hosts are upgrading from PHP 5.3 to PHP 5.4.21 on Friday and they have
   suggested I ensure that my website, run on WordPress 3.5, will be compatible?
 * Can anyone tell me if my site will be ok after the upgrade or if I need to do
   anything?
 * Thanks
    Claire

 * Try some Google searches for the names of your plugins and themes along with 
   php 5.4 and see what turns up.

 * You really should get WP updated – using an outdated version is a major security
   risk.

 * Thank you, I’ve updated my WordPress so hopefully that should mean I’m ok. Cheers.
