My sharepoint was recently migrated to a new server. Changed the url for all the pages. I have an important page that contains lists grouped by categories. I would frequently use the Edit button to move an item from one category. Since the migration, when I click the edit button it takes me to 'Page not found' as opposed to opening window that allows me to edit the item. I'm aware that I can create views but would love to keep the page as is but can't figure out how to make the edit button work.
I also have a 'Create New Item' button on the page which allows me to create a new item but even the newly created items go to "Page Not Found" after clicking the Edit button.
