First try disabling vbSEO and see if the 2nd page and further works. If it doesn't work, it almost have nothing to do with vbSEO. But if it does work, there should be a setting in vbSEO on URL settings and configurations. If you can't seem to toy with that (I personally never used vbSEO but ran a site that did use it and played with settings before). If there's nothing, just submit a support ticket with your host as it may be host related.
