Our theme is currently running jQuery 1.7.1, which is causing problems, so I’m testing what happens updating to 1.11.1. We’re using a customized version of the cMap template.
If I update the jQuery call to 1.11.1 the bio dropdown does not work using either cMap or our customized version. Both work when the jQuery call is 1.7.1.

I tried disabling the Bootstrap js call and turning off WPBakery Visual Composer, which is the only recent plugin change we’ve made. Neither fixes the issue.

Thanks, Susan

Connections is compatible with jQuery 1.11.1 (which is what is used on this site).

I suspect you may have multiple jQuery versions being loaded on the page which is actually causing the problem.

Looking at the page source I see this:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="/wp-content/themes/roots/js/libs/jquery-1.7.1.min.js"><\/script>')</script>

I would say this is a very bad way to handle this within WordPress. It’s always better to let WordPress manage jQuery and let it load the version that is bundled with WordPress. Loading jQuery via a CDN is fine when done correctly, it is just the above is not correct (for WordPress). This probably why you’re having problems with jQuery in general.

Here’s an excellent blog post which goes into deep detail:
https://pippinsplugins.com/why-loading-your-own-jquery-is-irresponsible/

Fixing this could be easy or tough…

First, I would remove the code I referenced above. My guess is that is it will be in the theme’s head.php or header.php file.

Now it seems some is de-enqueuing the bundled jQuery version. So this is the tough part. If you know what is de-enqueuing it, disable it. If you do not, Connections has something built in which attempts to fix this issue. Go to the Connections : Settings admin page and click the Advanced tab and enable the jQuery option.

Hopefully this fixing the issue.

If you wish to load jQuery from a CDN, use only this plugin:
https://wordpress.org/plugins/use-google-libraries/

Hope this helps! Let me know.

Thanks for the info and the link. I inherited the current jQuery setup and I’ve been trying to test what will break if I update. Enabling the jQuery option in Connections does fix the directory problem, but the list of other elements that break and conflicts I haven’t been able to isolate is growing as I investigate. Since we’ll be undergoing a major rebuild in the next 6 months I may have to hang on to the current setup til then.
Thanks again, Susan

@ Susan

Yeah, that does sound like the best option.
