Infinite SEO upgrade causes site to be unavailable

Hi,

I just upgraded to the latest version. When I did so there was an a site error msg, but I did not create a snapshot of the message. Indeed the site and my dashboard were not available (http 500 error). After renaming the Infinite SEO plugin folder my site was available.

I have a copy of the previous 1.3.1 plugin folder for restore so when I have time I will try to recreate.

Regards,
Larry
