Problem fixed when I upgraded. Screen options magically reappeared. The wonder of the web.
Thanks for the quick reply. Recent Drafts is showing but not revisions. It’s not an option from the Screen Options. Recent Drafts only shows the last saved version.
Something weird happening after upgrade. I can no longer see my published posts and pages from the admin screen (wp-admin/edit.php). They’re all up fine on the site and I can access them from there. (Tell a lie, I’ve now got an ‘Error 500 – Internal server error’ error, but it was working, however, only with the HTML view, not the WYSIWYG). New post and drafts come up fine (but, again, not the WYSIWYG). Any idea of the culprit file before I try the upgrade again? I have another site on WordPress.com and the admin screen looks completely different (and works perfectly of course) and on a different host, using their copy of WordPress. Any ideas?
