I'm just a few months into migrating a site for a friend. I have had a large number of pages imported already, but now that I have imported the last few it seems that I've crossed some limit that the admin interface is no longer able to handle. When opening up /admin, I'll get a blank page.
I really don't want to migrate to another CMS because of this, so I am wondering what can be done to give /admin some basic functionality. We don't even use the 'Site Content' tab to edit page content. There is really no reason for the admin page to load all pages as it seems to do. I could imagine making a new page type that does not inherit from SiteTree. What would be the wisest option here?
Thanks in advance,
