 * Plugin has worked great for a couple weeks. Today every page in the admin (and
   front) takes a long time to load, and scrolls forever with query monitor output.
   This red error appears above the Query Monitor output if I scroll far enough.
 * “A JavaScript problem on the page is preventing Query Monitor from working correctly.
   jQuery may have been blocked from loading.”
 * Just not sure why today all of sudden?

 * Thanks for the report. A new version of QM was released yesterday but it sounds
   like something in your site is causing it to break.
 * Is there a plugin or theme active on your site which is changing the way that
   jQuery loads?

 * Same problem here. jQuery-core is loaded fine in the same page’s source:
 * `<script type='text/javascript' src='https://neosmart.net/blog/wp-admin/load-
   scripts.php?c=0&load%5B%5D=jquery-core,jquery-migrate,utils&ver=4.9.5'></script
   >`
 * and `window.jQuery` is defined and working properly.

 * Thanks. It looks like I need to improve the way that QM’s fallback behaviour 
   works when it thinks that jQuery isn’t available.

 * Hi John,
 * It was actually a cache issue. A hard reload took care of it.
 * Thanks for your awesome work. It’s helped me provide feedback to literally dozens
   of popular plugins about bad query plans, lack of caching, needless script loading,
   and more.

 * Thanks for the update!
 * I’m still going to make the jQuery fallback handling better to improve this further.

 * Hi John,
 * I’m getting this same error at the bottom (footer) of my webpage. I recently 
   updated a bunch of plugins so I have no idea what is causing this.

 * 2 days ago I installed the plugin and was working fine. Suddenly today I started
   getting error in Query Monitor console
    `A JavaScript problem on the page is 
   preventing Query Monitor from working correctly. jQuery may have been blocked
   from loading.` It’s partially working. In my website code, jquery is still on
   top. I also tried to add async to jquery but that too doesnt help.

 * This should be fixed in 3.0.1
