NullReferenceException when installing new certificate

[sidahmed-achour]

Hello,

I'm trying to install new certificate using the extension, in the final step, after choosing the domains, setting the email and clicking on Next, a NullReferenceException occures and I get the yellow screen. I'm using the version 1.0.5 of the extension.
Here is the stack :

[NullReferenceException: Object reference not set to an instance of an object.]

I'm getting this exact error in 1.0.6. Any idea how to fix it?

I get this error when attempting to register a wildcard certificate. Let's Encrypt supports it, but does this extension?

[michael-lang]

Wildcard domains, see the alternate project:
