OpaqueResponseBlocking

Does anyone know what this error really means?

A resource is blocked by OpaqueResponseBlocking, please check browser console for details.

I've had an SEO "expert" tell me that Google can't see the page correctly. He sent me a link to Google's daily cache "snapshot". At first glance, it's missing all the linked CSS files and the images. Without even looking at the source code I suspected it wasn't using the base href for the page. When I viewed the source I saw the first thing was an incorrect base href in the first line before the actual source code of the page. Then within the source code of the page is the correct base href. Obviously, it's "obeying" the first one. Then I went and inspected the page in the browser Dev Tools and that's when I saw all of the missing items from the page were listed out with this message:

A resource is blocked by OpaqueResponseBlocking, please check browser console for details.

When the "expert" asked me “Leslie any ideas why google cannot see them?” I knew I was in trouble and thought I'd better come to the real experts.

FWIW - I have discovered that the demo of Shadows has this issue too. If you look at the Google cached version of the page:

https://webcache.googleusercontent.c...adythemes.com/

Then do a view source of that page. You will see that Google isn't happy and has added what it thinks should be the base href (I didn't add the highlighting - it was already there)

I have noticed that the cached version of a number of other Miva pages are "broken" due to this.

This is probably no longer an "Off Topic" issue but probably should be moved to the Miva 10 forum.

lesliekirk When Google caches a webpage they only cache the HTML which is why you see the Google cache pages render that way:

Can you ask the SEO expert why these pages need to be error free? I have not been able to find any documentation saying that this will effect the SEO of the website.

Excellent question Nick! I will ask. I have asked him "how" I'm supposed to fix it but have forgotten the "why?"

It seems that the SEO "expert" is concerned that what is happening to the cached version of the page is happening to the actual version.

lesliekirk I can assure you that the live version of shadows.mivareadythemes.com does not have a duplicate base herf. From the research that I have done Google is adding the duplicate base href

Here is a link I found about the Cache results:

Nick - the second base href is "injected" by the Google Cache. If you look at the screenshot I included you will see there are two:

This one is "injected" by the Google Cache

base href="https://shadows.mivareadythemes.com/"

and the expected one which is part of the template:

base href="https://shadows.mivareadythemes.com/mm5/"

I'm not saying the template has two base href - the Google Cache is injecting the second one. The question should be "why?"

More "stuff" pointed out by the expert (and I've found it too with the site in question)

in the Google Search Console I inspected a URL (just grabbed one at random that has been around for a while), then went to look at the Crawled page "More Info" and under Page resources, it shows a list of items that "couldn't be loaded" - they were all images for that page. If you go to the page, the images are there. Why is Google saying they "couldn't be loaded"?

This is different from the two base hrefs but could it be why Google "thinks" the page needs one and tries to insert one in the cached version?

To say the least, this SEO guy is claiming that this is a BIG deal.
