Php 4.4.2->5.0?

[Pyrofyr]

Well, I need 5+ to run a wiki on my website (Which I plan to do under a subdomain) however Bluehost set me up with 4.4.2, is there anyway to upgrade?

Also, will it mess up my vBulletin forums I have setup? (1.6.5)

Would I have to contact them directly for this upgrade? And if so, how?

send in your upgrade request to bluehost support.

for the forum you running. as usualy upward upgrading should be fine.
