I updated the theme to 2.4 (had pre-2.0 something before). During which I was prompted to update Theme Post Types from 0.1 version to 1.1. I did that and after updating I was asked to activate the plugin. This cannot be done as it says I do not have rights to view the page that tries to open. I have highest level admin access. Any ideas?
It is very strange that administrator doesn’t have access to activate the plugin. But it can’t be a plugin issue, probably something with your WordPress configuration. Anyway, you can continue using the first version, 1.1 doesn’t have too many changes.
