Wow, I knew I needed a vacation. This is an epic case of faking myself out, but it's going to have a happy ending.
Ok, so part of the confusion has been coming from the text placed directly into the page, originally intended as a staging area for populating your plugin. This site has had a really drawn out timeline with a number of extended interruptions. I had forgotten the staging had ever occurred, believing I had completely switched to the plugin. Apologies for mixing you up in that.
The good part is that now I have another page set up to finish out what I had begun. Your setup is an improvement, and I have *almost* everything styled to match the site now.
There is one last thing I would like to change, and I don't know if this is coming from the plugin or WordPress. The icon/bar in front of the blockquote is stubbornly grey. I would like to either change it's color or replace it with a different icon. I have run out of time for the day to experiment with background images, the only thing I can think of that I see in my reading.
Can you point me in the right direction for that? If not, I understand. Either way my client is going to be a happy HMS Testimonial user. Thanks for your patience!
