I have a portfolio page that comprises a number of individual project posts - http://krconsult.co.uk/portfolio/.
Yesterday I upgraded WordPress SEO to version 1.4.13 and discovered that it was causing a conflict with my project posts effectively blocking them - making them undiscoverable and creating 404 errors. When I deactivated the plugin, the problem disappeared.
Any suggestions or remedies as I haven't experienced this before with earlier versions?
Thanks in advance for your help.
