I keep getting the warning message about "Lost session data" when I go to save changes at EN. This was a problem a few months ago, then was fixed, but seems to be back. However there's a twist:
1) I click save (with an edit summary) 2) Preview comes up with message "Sorry! We could not process your edit due to a loss of session data. Please try again. If it still doesn't work, try logging out and logging back in." - edt summary box still has my summary in it 3) I click save 4) Reminder: You have not provided an edit summary. If you click Save again, your edit will be saved without one. 5) Save again - works.
On one or two instances, the lost session data error message has appeared twice in a row.
