I have 3 instances of your template running.. On each instance I have only 1 plugin installed. Those plugins are different real estate related plugins.. I 'm doing testing.
On each instance, the error occurs with a different plugin.
Please stop wrapping your links in code blocks to make them non-clickable; the club boards are only visible to paid members, so you don't have to worry about spambots.
If the file you attached in your most recent post is the file from this site, I would guess that the line(s) needing to be commented out are in the "helpers/js.php" file of the plugin.
This one is working fine for me.
In other words, we are 3 for 3 of installing a plugin on a the template and having the error occur. Where would I begin to look into commenting out jQuery in these plugins? Sorry, but I am used to Joomla, and a noob for WP. Any advise on what and where to look?
I'm sure I will be adding other plugins that use js along the way as well.
I'm not sure about 3 for 3; the second site works fine for me.
The line you'll be wanting to look for and comment out will be something along the lines of "wp_enqueue_script('jquery')"... it may have slightly different arguments.
As I said, a patch to prevent the duplicate jQuery issue is top priority and should be ready early next month, I just have to figure out the best method.
