I've installed and tested the plugin and all seems to be working except when in the wp-admin clicking --> constant contact --> contacts
It takes about 2 full minutes then times out with a 500 error. All other menu items work as expected.
WP version 3.5
PHP Version 5.3.14
Linux p3nlhg146.shr.prod.phx3.secureserver.net 2.6.32-279.14.1.el6.x86_64 #1 SMP Tue Nov 6 23:43:09 UTC 2012 x86_64
Thanks for any pointers.
