So, if you see that error, then that’s the currently active/used PHP version. Some hosting providers let you choose a version in their dashboard. Make sure you select version 5.3 or newer and make sure that it works (eg. Godaddy’s switch doesn’t always work). Some hosters take some time to apply the new version, often up to 36 hours.
