yesterday did a fresh install of 2.4 and made a few modifications to some content on the default pages.
today, when i go to access the pages, a browser error box pops up with title "the page http://myurl.com says:" but there is no text within the message box.
when i close it, silverstripe admin page generates an error at the bottom, in red, "error loading page"
basically i cannot add or modify any pages.
