I am trying to run the version 9.03 mysql version.

I had a Access version 8 database, which I first updated to version 9, before I migrated it to Mysql. The first hours when I did some testing it worked fine, now since this morning I get:

Microsoft VBScript runtime error '800a005e'

Invalid use of Null: 'CInt'

A re-sync of topics didn't help.

What must I do ?

Moving between database version often doesn't work. May advise would be to lock your old Access version and use it as an archive forum and start again with a new forum, using the import tools in version 9 to import your users from your Access database.

If you want to try and continue on with the mySQL migrated forum have a look and make sure that the default values have been created in the database. Also, for things like Access true/false fields, mySQL dose not have a corresponding data type so you need to use a TinyInt instead.
