Upfront not allowing pages to be created

Hi there! I am having issues adding pages to my site. I have found that if I add a page via the dashboard that I get a string of error messages across the top of the page. So, I deleted all pages from my dashboard. When I try to create pages within the editor, the process seems to not be able to complete as the wait graphic continues to spin for several minutes before I have to force it to back out.
