This question already has an answer here:
First time I've ever needed to ask a question here that I don't think has already been answered.
I've recently been working on transferring over a vBulletin site I run to a new server. Thinking that I was being all ahead of the curve, when I went to install Ubuntu on it recently and saw 14.04 was available, I went for it.
As I should have expected, it's a nightmare. Turns out that vBulletin JUST added support for PHP 5.4 with their last release on the version I run. I honestly don't expect them to ever get it up to PHP 5.5 (what 14.04 installs by default).
Save from going back to 12.04 LTS and starting completely over, is there a way I can downgrade the PHP version installed to 5.4? I saw some threads talking about this for going from 5.4 to 5.3, so I'm hoping its doable.
The simpler you can help me to do this, if possible, the better. I know my way around, but by no means consider myself an expert. Thanks!
EDIT: For clarity. Need to downgrade PHP from 5.5 to 5.4 on 14.04 (Trusty Tahr).
