First of, I'm not overly technical.

My web-hosting company has suddenly started charging me US$8.71 a month for php support, without me asking for it.

Does Xara use or need php? I have WD11 Premium.

From what I can make out, my account is setup to use php 5.6, but it's apparently outdated, so now I'm being charged for additional support.
The web-host has listed all my domains as using php 5.6 - even those that are not even being used, but registered with the web-host.

Am I being taken for a ride, or is "php extended support" necessary?
