We have found this can happen if optimizepress is not installed properly. if you look your themes page, you will probably see that the location for the theme is something other than /OptimizePress
if it has a number next to it or some other text after the “OptimizePress” then some features wont work correctly
To fix this you need to activate the default theme, delete the existing optimizepress theme and upload the zip file again. You can also follow the steps here:http://www.optimizepress.com/update
You should also check the installation directory of OptimizePress. It must be installed inside
If you see any other extra directories, your installation wont work properly. You need to modify the theme folder location via FTP, or get your hosting company to do this for you if you dont know how to use FTP.
