Configuration and Customisation Problems

1. First of all, check that both checkERW.php and checkdb.php do not report any error about your ERW configuration and database content. In particular, if you upgraded from a version without original filenames, a missing column original will be reported in each fileset. Please regenerate the SQL code to see how these columns should be created.

2. If you have custom files, remove them gradually, so that you can tell whether the problem is caused by a customisation or by a hook.
