The original site at content.ultimateseo.org was hacked preventing its further usage. Rather than restoring the site with the same technology the site was replaced by a WordPress based site.
The original application required PHP 5.6 which is outdated and lent itself to vulnerabilities. It had been our hope the site wouldn’t attract exploiters but obviously this was an underassessment of some people’s boredom.
The new site is not yet operational but upon completion it will again offer free posting of guest posts to the site and webmasters will be allowed access to the content feeds by category for auto posting syndicated content using RSS feeds.
