Hi All, I'm consistently getting the error in the subject line (or close variants--some actions get further than executeAction() before throwing a "Class not found") when attempting to use _any_ API action other than query (which works fine). I've tried it on two 1.11 installs on machines with totally different php setups. I'm using repo directory revision 35899 of the API. Thanks for any light you can shed on this baffling and frustrating problem. CYa, JEREMY
