Hi, we have been informed by our host providers that support for PHP 5.2-5.4 is at an end. Our sites are currently made via RW 6 with themes Serenade by BLT and Flood by theme Flood. How do we go about getting the PHP upgraded to latest versions, upgrade to RW7 use different themes, use either Foundry or Foundation? Apologies if this is a dumb question but don't know how this works (obviously!). Here's screen grab of message from Fasthosts our providers.
