Fist Full of Crisco

jquery error might be an ordering issue. meaning, jquery is being combined into the file after someone who needs it. jquery should come first. u can use manual mode to set the proper order or do it via code.
I have no problems.

For me i also relocated my wp-config.php for security reasons but you seem to be doing it wrong. To save me time i just found a guide that outlines the correct way:
https://www.groovypost.com/howto/improve-wordpress-securitty-wp-config-php-location/

You beat me to the answer ??

then you are misunderstanding the article. It makes a significant difference.

1. Have you checked to see that your js/css files are combined and minified and placed at the bottom of the page?

2. Are you using browser caching?

3. How many other resources are you loading on the page?

4. Be careful when using object and dbase caching. They can slow your site if configued incorrectly.

Just checked your page. I dont see the problem. All your css and js files are coming from your CDN only; nothing local.

1. iframe contents are only displayed at runtime within the client’s browser, not server-side, therefore can’t be cached.

2. PDFs are loaded and interpreted by the client’s browser (internally or as an extension/plugin), not server-side, therefore can’t be cached.

If you want it cached then i recommend dropping iframe and using some tool on your server-side that can read and display pdf content as html so you can then embed it on the page prior to sending it to the client’s browser.

Looks good to me

Might be wiser to have it before, if u plan on enabling the ssl caching option in w3tc in the future.

Btw, it might be preference, but, alternatively, you can replace this

RewriteCond %{SERVER_PORT} 80

with

RewriteCond %{HTTPS} off

.. as a way to make it clearer what you are doing.

Are you using Content-Security Policy (CSP) rules? Just wondering if they might be misconfigured (too restricted). If its not enabled then disregard what i said.

Curious, why are you caching the wp admin(?) login page? Typically, most people dont cache that page. I figure the issue is the use of a ‘nonce’ which is getting cached. Shame developers don’t use ajax more often knowing that most sites will sooner or later make use of caching software.

So i doubt its a bug in w3tc and actually short-sited software makers not taking into consideration the existence of caching tools.

good money says u are using object caching and/or database caching.

regex is your friend.
at least in the w3tc community edition it supports full regex. i could have sworn the official version also supported it. regex is far more superior to simple wildcards.

It means you’re not using the multi-user version of wordpress. In short, it shoudl say “off” if you aren’t using that feature. For example mine says “off” and its working fine because i am using w3tc to handle my single site.

Works 100% fine for me and i am using an earlier (custom) w3tc version, not 0.9.7. Likely its a compatibility issue with a different plugin, not w3tc.

Sounds like you are using the precache loader, whereby you are having w3tc recache pages after a certain time. Seems like a dik move by your provider blocking loopback http requests. You could use a proxy to get around this problem.
