Increase of AMP validation errors: invalid value of ‘src’ attribute

Can you please share your website URL? So we can analyze it and help you fix the issue for you.

Hi, thank you for your reply. I have three sites using the plugin, same issue on the three. Those pages use the plugin:

– https://bit.ly/2GmQUsS
– https://bit.ly/3aGXlFb

Thank you!

We checked your issue. This issue is not coming from our plugin. On your website, there is adding a defer attribute on your page. so you have to get that error.

AMP is not supported by this defer attribute. This defer is coming because of using some cache plugin. Can you please deactivate all cache plugin and clear cache. Then activate one by one. Then you have to understand which plugin causes this error.

Hi, found the source of the issue. It’s not a plugin, it’s actually a function for deferring the parsing of JavaScript. Not sure why it’s started to cause problems now (I’ve been using the plugin and the function for a couple of years).

if (!(is_admin() )) {
function defer_parsing_of_js( $url )
{
    if(FALSE === strpos( $url, '.js') || ((strpos( $url, 'jquery.ui.core.min') > 0) || (strpos($url, 'jquery.min') > 0))){ 
        return $url;
    }
    else{
        return "$url' defer='defer";        
    }
}
add_filter( 'clean_url', 'defer_parsing_of_js', 11, 1 );
}

This code is not working on AMP. Because AMP could not support the defer attribute. It is working on Non-AMP. So can you please remove this code from AMP? And check once whether having the same issue or not.

Hi, as I mentioned the problem is solved when removing the code ?? I’m just wondering why it used to work well before (I’ve been using this code and your plugin for several years and never had any problem until this January).

Is there a way to exclude the AMP version from the code?

Such as if (!(is_amp() )) { or something similar?

Thanks! By the way, the plugin is really excellent!

Thank you so much for using our plugin.
