Items not Adding

So I am new to omeka and don't have a coding background, but I have a friend that does. We've been working with omeka for a school project but now have come across a couple problems.

I can't add an item on the admin site. Every time I try to save an uploaded file, it said "Omeka has encountered an error" and then "Dropbox not working" or something like that. So I went into the plugins on the admin website and deactivated the Dropbox plugin to see if that would help. That solved that problem but no it says something like "Zend_Http_Client_Exception - Passed parameter is not a valid HTTP URI."

We think this has to do with the server we have put our omeka on. We originally received server space through our school, but the php version and such on the server was extremely out-dated so we had to do a bunch of uploading new versions. Neither of us had ever done it before so it was extremely long and hard, and most of the ways to upload the server stuff was based on google sites and blogs we could find.

We think the error has to do with our php that we had to upload, but we're not sure what to do next. Any help would be greatly appreciated!

If you're getting an error now, it'll be helpful to post what URL you're at when you get the error, what you were doing or trying to do, and the full text of the error.

The URL I get when I try to add an item is: http://icexmalta.csc.calpoly.edu/omeka/items/show/1

The Full text of the error is long, but here it is:

You need to successfully configure the Scripto plugin or disable it.

Awesome it works now thank you so much!
