This is driving me crazy. It's working when I run it in Visual Studio, but not when I deploy to Azure.

I'm getting the following error in the tracelog:

It seems to be related to the gateways. I disabled all the gateways in Merchello and republished, and I'm not getting those errors.

I haven't been able to re-enable them again though.

Is there any guidance or best practice related to deploying from VS to Azure?

I deploy to Azure from VS without problem.

Make sure your App_Data / App_Plugins folders are included in your solution otherwise they won't get deployed.

Milton,

What type of Azure service are you deploying to?  Websites, VM, etc?

Are the Examine Indexes correctly filled?

It appears that its an issue with encryption, but I'm not sure what that would be.  Might have to ping Rusty on that.

Thanks,
Jason
