SSL Cert Installation problems after update

After updating to WHM 11.26.8 over the weekend, I'm now having issues with installing SSL certificates. Enom is bouncing the CSRs with the following error:

An error occurred: [CODE: -2023] [MESSAGE: CSR contains unsupported extensions.]
An error occurred: [CODE: -2023] [MESSAGE: CSR contains unsupported extensions.]
The thing is I'm using the same method I've used for years, nothing has changed but the WHM update. I've tried selecting all of the apache SSL types and even the cpanel csr type on enom with the same results.

Anyone else having this issue?

I got this on eNom's website:

Error: "unsupported extensions" with CSR code
Answer ID 109
Why did I get "unsupported extensions: when I enter my CSR code?

If you are generating your CSR either from WHM or another Linux based server, you need to put the challenge passphrase (password) all in alphanumeric.

GeoTrust or SBS will return the error, "Unsupported Extensions," if you're entering non-alphanumeric characters. We pass the error messages directly from the certificate authorities, so the error text may sometimes be confusing.
