I just transfered my Concrete5 site from a working GoDaddy Shared host to a VPS. I've got a dev version online, but I'm noticing some strange behaviors.

The first one, which is being caused by a php or a javascript error:
I cannot see that header_required and footer_required are being included on the landing (index.php) page. Also, some blocks are not rendering. If I go to any other page on the site I see the dashboard as usual, but on the landing page I see only my header.php, and some of the home.php (which is the pagetype) (same thing with schools/high-school)

Second thing:
When I go to add a block on another page in the site which allows editing, I get a forever spinning wheel when I try to save it. In addition, when I try to upload a file using the file manager it hangs there too. But here's the strange thing: when I go look in my DB, I see that the block has been added to the database (if it's a contentLocal blocktype, I see it in that table). and if I refresh the page, I see that the block has been added.

I am able to clear the cache, run automated jobs, sign in sign out, etc. The site did not have these problems before the migration, it was just a little slow.

I am running the latest stable version of C5 (5.6.0.2). If you want to look at source, go tohttp://www.dev.waldenschool.us

EDIT: I've almost isolated the problem... I have a DC block that I created, and if I create a new page and add that block, it breaks the page. I don't understand why, because this block was working fine on the other site, and there are non of this block on the home page.
