I installed mediawiki 1.5.6 and 1.4.14. In the both wikis I had the same problem: When a logged member edit and save a page, He gets the following error message, "Note: Remember that this is only a preview, and has not yet been saved!". But a anonymous users can edit and save the pages normally.
PHP's session storage is broken. Probably one of the following is true:
1) You are running on a Windows server, and php.ini has the default setting of "/tmp" for the session storage path, a directory which does not usually exist on Windows.
2) You are running on SourceForge.net's server farm or a similar setup where php.ini has the default setting of "/tmp" fo rthe session storage path, a local directory which is different for each server that a user hits.
Fix php.ini or see the FAQ entries on SourceForge.
