[TYPO3] edit page properties : blank page

I didn't really follow this thread, so I may say something out of  
topic here, but this behaviour does ring a bell.

In one installation I suddenly had records (pages, content elements,  
whatever) that I could not edit. The problem was that they had a uid  
of 0.

This happened after migration down from a MySQL 5 to a MySQL 4  
database. In generating a v4 compatible SQL dump from v5 database,  
the auto-increment properties of the uid fields are stripped. Thus  
new records are created with primary keys = 0. To correct this it is  
sufficient to go to the Install tool, compare the database and  
perform the required updates. This behavious is documented in the bug  
tracker:
