[Help Wordpress] RoyalSlider works locally, but when deployed to a remote test server, is generating an error message

So I have a WP installation with a custom theme that I'm working on.

When I run the site locally, I'm not having any problems displaying a RoyalSlider on one of the pages, either when I have it displayed in a special content area (passed into the template as a custom field), or when I directly include the shortcode in the page content.

However... when I publish the code branch out to a remote site that we use for testing, in place of the slider, I'm getting the "[RoyalSlider Error] Incorrect RoyalSlider ID in shortcode or problem with query." message. I've tested it where I include the call for the slider in the special content area, as well as within a page directly via shortcode, but it ends up with the same result.

There are no javascript errors on the page, nor are there any PHP errors or warnings, so no obvious culprits.

Troubleshooting Steps (so far):

1. Deactivate and reactivate RoyalSlider plugin
   


2. Delete and then recreate the slider that is being referenced through the shortcode to make sure that it exists.
   


3. Create a new slider, with a different ID to ensure that there wasn't something strange with the database / metadata for the previous slider
   


4. I've tested the slider loaded via shortcode, and directly from PHP

Alas, none of those steps made a difference.

Any suggestions on other ways I can troubleshoot what the message is referring to? Thank you in advance!

For reference:
WP version: 3.5.1
New RoyalSlider version: 3.0.3
