Big PHP error when enable Wymeditor

Hi all,

I have a big PHP error when I want to create, edit a node in which I have WymEditor (the error appears even if Wymeditor is disabled by default).

    * warning: Invalid argument supplied for foreach() in D:\mySite\www\modules\node\node.module on line 504.
    * warning: implode() [function.implode]: Bad arguments. in D:\mySite\www\modules\node\node.module on line 508.
    * user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 query: SELECT n.nid, n.vid, n.type, n.status, n.created, n.changed, n.comment, n.promote, n.sticky, r.timestamp AS revision_timestamp, r.title, r.body, r.teaser, r.log, r.format, u.uid, u.name, u.picture, u.data FROM dp_node n INNER JOIN dp_users u ON u.uid = n.uid INNER JOIN dp_node_revisions r ON r.vid = n.vid WHERE in D:\mySite\www\includes\database.mysqli.inc on line 151.

any ideas ?
