Suddenly a problem with Amazon SES

[MARK L HUNNIBELL]

Hello
I have a licensed installation of Newsletter 7.1.4 that I had successfully been using to send out a few newsletters a month to a couple hundred recipients using the Amazon SES extension. Once the cron picks up the job to send, all 200 go out in a second or two.
It has been quiet for the last two months, so no newsletters. But now we need to send one. I usually send a test of the newsletter to a small group of 3 to make sure the link work, etc., but last night it did not work.
It took an extraordinarily long time to SAY that it sent them… one by one… about 10 minutes between each, but they were never received.
On the “Newsletter Amazon SES Integration” page (“newsletter_amazon_index”), it has a semi-warning banner at the top that says:
The Amazon Services connection kit is already included by another plugin. There should be no problems if they load the whole Amazon SDK.
I have no idea what happened, but something has come loose somewhere. I have this site on a hosting service that hosts many other sites, but I cannot see any indication in my WordPress plugins that a separate installation of Amazon Service connection exists.
I have written a support ticket, but I have not heard back. This is a real problem for us because it is a time-sensitive newsletter that should have been sent yesterday.
DEBUG log is below.
Thanks in advance,
Mark

OK… so I did not hear from anyone but kept probing and found the problem.

The problem was that another plugin I had installed (Total Upkeep) had an internal “hook” to Amazon AWS presumably to store backup copies if you have an account. But I was not using that Amazon AWS feature in Total Upkeep/

I disabled the Total Upkeep plugin (there was no means I saw to disable the Amazon AWS feature).

PRESTO! Back in business!
