* Hello guys, I installed the amp plugin some weeks back and I have some issues
I’ll appreciate if you can help me fix.
* My search console showed.
* The attribute ‘frameborder’ in tag ‘amp-iframe’ is set to the invalid value ”.
* The attribute ‘frameborder’ in tag ‘iframe’ is set to the invalid value ”.
* The error effects 45 pages and I have verified the errors via amp validator.
* I will appreciate it if you can help me fix these issue. I have attached a URL
to a page with such an issue, I believe if if I fix these one I can fix the rest.
* The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Famp-validation-issues%2F%3Foutput_format%3Dmd&locale=en_US)

* In the non-AMP version of that page, I can see an `iframe` defined as:
* ```
```
* Note the `frameborder` attribute has no value provided. Even so, if I try that
my machine I get this result:
* `...
`
* So the value is getting supplied. Nevertheless, your site is removing the value
from the attribute. I also see that all attributes have quotes being removed.
* Do you have some optimization plugin or server module that is doing this? It
seems to be making the pages invalid AMP.

* I am not sure, the only optimization plugins I have is:
* W3 total cache
* Other plugins on my site include:
Ads inserter Ads for wp AdSense invalid click
protector Amp Better WordPress google sitemap Classic editor GDPR cookie consent
Glue for yoast Inline related post Jetpack One signal Powerkit Seo framework
Seo framework manager

* Ok, please try deactivating W3 Total Cache and see if that eliminates the issue.
If so, there is probably a way to configure the plugin to not minify the HTML.

* Sorry for the late reply, w3 total cache was causing the error, it was not only
striping my iframes of ‘frameborder’ but also my videos of ‘name’, ‘description’
etc, causing a lot of errors in my search console.
* Everything is fine now, thank you!!!

* Excellent. I believe you’d be able to fix this also by disabling the “HTML minify”
in the W3 Total Cache settings.

* Hello [@westonruter](https://wordpress.org/support/users/westonruter/) [@hycent](https://wordpress.org/support/users/hycent/)
I am Marko, W3 Total Cache support. I am sorry about the issue you are experiencing
when HTML minify is enabled. Can you please apply this [fix](https://github.com/W3EDGE/w3-total-cache/commit/f0faeb5cc3e2b807f153327c62a8d3c365e2757a#diff-9cea5333909e4ce25c7c3a5056c00737R356):
and replace line 356 in lib/Minify/Minify/HTML.php `if ( empty( $m[3] ) ) {`
with `if ( $m[3] === '' ) {`
* Please let us know if this helps!
