I just upgraded from 4.6 to 5.2(i think) i followed all the correct steps, ran upgrade.php and updated all the modules with no errors. Almost everything is working, but some nodes are coming up completely blank. All the CCK Field data is gone. When it was installed in 4.6 i did use node revisions from time to time. Looking into the Database all the content is still there, the correct nid and vid are associated -- it just doesn't want to show up.

also some node types are blank, others are not. One nodetype has the 10 most recent created nodes blank, the rest are fine.

Anyone have any idea what might be going on here?

Thanks.
