Hi there,

I think installed the mod okay. I tested it by sending the confirmation to my email.

However, when I was going to the "USAGE INSTRUCTIONS" in the Read Me file, I didn't seem to get through to this point:

Under 'Tools -> Send Email' you'll see new customer groups:
Email Test Group - Customers
Email Test Group - Newsletter-only subscribers
These two fields pull the correct emails you designated in your
Newsletter Test Group Email settings.

Newsletter Subscribers
Customer Account Newsletter Subscribers
Newsletter-only Subscribers

I don't see new customer groups or Newsletter Subscribers under 'Tools -> Send Email'.

Rather, under Tools ->Send Email, it says:
"Send Email To Customers Text Editor

1267 Illegal mix of collations (latin1_general_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation 'locate'
in:
[SELECT s.email_address as customers_email_address FROM subscribers as s LEFT JOIN configuration as q on LOCATE( s.email_address, q.configuration_value) >= 1 WHERE configuration_key = 'NEWSONLY_SUBSCRIPTION_TEST_GROUP' ]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields."

What does this mean? Can someone please help? Thank you.
