Page Management Partially Loads

When I click the ‘Pages’ option in the ‘Manage’ section, only the first part of the ‘Page Management’ page opens; the box appears with the text “Pages are like posts except they live outside of the normal blog chronology and can be hierarchical. You can use pages to organize and manage any amount of content.” but nothing underneath! There is nothing else on the screen, not even the WordPress logo which appears at the foot of the other options. I have already created 3 pages which are still available when users browse the site.

When I check the HTML source code for the page, it appears that only half the coding has been loaded by the browser, yet the browser says ‘Done’ at the bottom.

This feature *used* to work, but no longer does. It worked for a short time on my work PC this morning, but now does the same as my home PC has done since last night – both now won’t show the Page Management option properly. The ‘Manage Posts’ page displays properly, however!

The account and pages are with ‘Edublogs.org’ and not hosted privately on another server.

Does anyone have any suggestions? Thanks in advance.
