I'm using a fresh WordPress 3.1 with WordPress Wiki (last version) on it. I had to transfer a load of pages in the wiki and it went pretty well but when I wanted to show the list of pages in the Admin the Wiki Page was totally blank and the "Add New Wiki Page" was empty (with menus, widgets on the side but no editor, nothing in the middle column)
So I changed all wiki pages to pages by changing post_type to "page" using phpMyAdmin... I then progressively changed theses pages back to "wiki" and I discovered that until I reach 2334 wiki pages, everything is going well... by the 2335th wiki page, the "Wiki Page" (/wp-admin/edit.php?post_type=wiki) is going blank again ... I thought the problem came from the sql entry but unfortunately no. Whatever other page I turn into a wiki, the Wiki Page goes blank and I can't do anything ...
Is there a limit or something ? Could it be related to my server's memory ?
Thank you everyone.
