Yes, the 'vuln_type' is a reference used by SCP info module and also for the firewall itself to look for vulnerabilities. Maybe you can solve this by
disabling the extension
and reinstalling it.
Thanks Jose, disabling all SCP extensions allowed me access to the site.
I did uninstall and then do a fresh re-install but got some more errors. PHPMyAdmin showed SCP installed and enabled, admin menu had no SCP entry and a direct link to SCP gave an error.
This is a site that I'm putting a new template on so I think it may be best to use the Quickstart template as a new site and add the content fresh, then install SCP.
Thanks
