Step 3: Run an Integrity Check
Next we want to run an Integrity Check.
ACP -> Core -> Core -> Tools -> Integrity Check
This will kick off some low level database schema update code that will do some work on the underlying database tables on your site. This could take up to 15 minutes or so to run
on very large sites, so please be patient.
If you feel that the Integrity Check has "paused" you can refresh and re-run it.
