"auto increment" issue

@bboran:

my "auto increment" on primary keys are gone by their self?
I doubt it. Though maybe someone proficient with wordpress might give you some pointers.

If indeed the problem is because there is no 'auto increment', correcting the database scheme/structure should resolve that problem. If nothing else, you can backup/dump the database data and import it with the correct database structure/schema.

I agree with travis, backup your database, reinstall it from the wordpress installer, then load all the data back into the new database, remember to skip create table statements when dumping the database and to truncate the tables before you load the backup. Missing auto increment is a bit weird not sure why it would happen.
