Concrete5 site crash

Permalink
My server updated the PHP files to the hosting plan last night, and now the website shows a bunch of code. I cannot figure out how to get rid of it. They have said it is has nothing to do with them and has to do with Concrete5.

I do not understand PHP, nor can I try and code it. I figure the websites concrete code needs to be upgraded but I have tried to do that using this method found here:http://www.concrete5.org/documentation/how-tos/developers/manually-...
and it didn't work. I cannot even log in to the site now!!! The site I manage uses Concrete5 5.4.2.2. I haven't upgraded it because I do not know Concrete5 very well at all and just took over the site in May 2015. I manage it for free for a high school band because my daughter is in the band and I am in their booster club so it is my contribution. The site name is svhsband.com.

Please, I beg anyone to help me with this!!! The parents.of the band students check the website all the time for updates and information regarding the band so it is critical that I get it up and running soon.

PLEASE HELP!!!

The site appears to be up and functioning, did you get this figured out or is it only broken when you are logged in?

Yes, I did get it figured out. I had been trying all day Saturday with Dreamhost and Concrete5 community to get it figured out. I finally got someone from Dreamhost on a chat session that knew what they were doing and he helped me revert my PHP back to 5.3. Therefore, the site works for now but their servers will discontinue PHP 5.3 as of January 1, 2015, which means I will have to upgrade concrete5, and that scares me :-(

Thanks for your response :-)
