This is on a authenticate to view wiki
Steps to reproduce:
(1) Edit a page and save
(2) Immediately edit the page again.
The edit window that comes up contains the text to the original page, not the current version. If you then make a change and try to save the conflict catcher returns to to the edit page with the changes you made highlighted as conflicting with the current version.
If you immediately shift-reload the browser window after entering the edit window then you receive the (correct) current version and saving obviously doesn't generate the conflict. The browser is clearly caching the edit page inappropriately.
This problem occurs with both Safari 3 and Firefox 3 with phpWiki 1.3.14 using MySQL to store the pages.
