Forum:New pages and modifications invisible for guest

Hello, since last day i've a problem with my wikia.

I try to add some pages and modif others, each actions are ok for me as an administrator but my visitors can't see any new pages or modifications I do. I try to deconect from my admin account and see my wikia as a guest and.. all my contribution are invisible, but i can find new pages by searching bar, but all modifications on existing pages are not visible.

On index page, in the top, i can see 15 pages when I'm logged on admin account but only 11 when I disconnect.

Some one have any idea about this? Don't know if this can help but, I tried to modif the MediaWiki:Common.js for the show/hide fonction and I think the problem appear after this.

Thank in advance for your help.

Ok thank you for answer, i'll inform my users ;)

Is there an aproximation about the cache refresh time? Same for registred users?
 * The cache takes longer to clear for anonymous users. It should show soon. 11:39, August 31, 2011 (UTC)
 * A few hours, maybe a day, perhaps. I don't know exactly. 11:58, August 31, 2011 (UTC)
