[Mediawiki-l] Warning: ignore_user_abort() has been disabled for security reasons

[Frames Project]

Hello

I just installed a new mediawiki (version 1.14.0)

I export/import some pages from an other mediawiki 1.14.0
When I save (some, not all, pages) I get this message :

Warning: ignore_user_abort() has been disabled for security reasons in /home/xxx/public_html/mediawiki/includes/Article.php on line 1513

What does that mean ?
What can I do to fix it ?

Thanks
