Updating to WordPress 4.5.2: jQuery Version Different?

Resolved Adam

The front-end of my site functions strange when I’m logged in, but when I log out, it functions fine. I noticed this just today when I updated from 4.4.x to 4.5.2.

I looked at the jQuery versions when logged in and out, and they’re different. Is this normal?

When I’m logged In, the jQuery version is 1.12.3. HTML:

<script type='text/javascript' src='http://example.com/wp-includes/js/jquery/jquery.js?ver=1.12.3'></script>

When I’m logged Out, the jQuery version is 1.11.3. HTML:

<script type='text/javascript' src='http://example.com/wp-includes/js/jquery/jquery.js'></script>

This may be the issue. Help!

The part “?ver=1.12.3” is only a reference to the jQuery version, it doesn’t really make a difference. Hence, all these as the same versions of jQuery:

http://example.com/wp-includes/js/jquery/jquery.js?ver=1.12.3
http://example.com/wp-includes/js/jquery/jquery.js?ver=1.11.3
http://example.com/wp-includes/js/jquery/jquery.js?ver=0.1.2.3.4
http://example.com/wp-includes/js/jquery/jquery.js?ver=99999
http://example.com/wp-includes/js/jquery/jquery.js?ver=axlrose

As long as it’s the same file (regardless of the “ver” variable), things should be working fine.

Though technically, there shouldn’t be a difference between logged in or logged out. Does this happen on any theme you use?

Thank you for the quick response, Mark!

I looked at the contents of each jQuery file my site was referencing, and the code is different in each file. It’s definitely using 2 different versions of jQuery: 1.11.3 when logged out and 1.12.3 when logged in.

I’ll try deactivating my plugins and switch to a WordPress theme (like Twenty Sixteen) to see if that clears anything up. I’ll let you know what I find.

Thanks again!

I changed the jQuery enqueue to load specifically jQuery 1.11.3, and my site works as intended. However, when I remove the code to enqueue the latest jQuery that ships with WordPress (currently 1.12.3), the site breaks. Is there a bug with the latest jQuery?

By the way, the issue now occurs whether I’m logged in OR out. I cleared my browser cache.
