For me, it looks the issue is I’m deferring the JS. * I used the testing tool at [https://search.google.com/test/amp](https://search.google.com/test/amp) * If I plug your page in this tool, I also see the error about “defer” Line 31. * I’m not using the same AMP plugin you are, but I do have some plugins that defer scripts. I’m thinking that may be my issue. * [prodport](https://wordpress.org/support/users/prodport/) * (@prodport) * [8 years, 1 month ago](https://wordpress.org/support/topic/disallowed-attribute-errors-on-random-posts/#post-10267119) * Just a follow up. My staging site showed no errors so I figured it was a plugin setting. * I had a plugin called “**Async JavaScript**” that my host had installed. I changed is so the AMP scripts that were showing as “defer” were changed to “async”. That cleared the issue for me and the pages validate. * **But the Google test page I referenced above seems to hold on to a cached version.** I had to go back to Google Search Console, click into the page with issues and then click “**TEST LIVE VERSION**” at the bottom right. It’s on that Issue Detail panel. * Thread Starter [Scott](https://wordpress.org/support/users/magius72/) * (@magius72) * [8 years, 1 month ago](https://wordpress.org/support/topic/disallowed-attribute-errors-on-random-posts/#post-10267303) * I’m using a similar concatenation/minification plugin called Fast Velocity Minify. * I can input files to not minify in the plugin options — which I’m guessing would fix this issue — but not sure what files/paths to put there… (like, what file does this refer to: amp-mustache extension .js script ?) - This reply was modified 8 years, 1 month ago by [Scott](https://wordpress.org/support/users/magius72/). * [prodport](https://wordpress.org/support/users/prodport/) * (@prodport) * [8 years, 1 month ago](https://wordpress.org/support/topic/disallowed-attribute-errors-on-random-posts/#post-10267450) * On my Google Search Console, if I click through to a URL and the Issue Details panel, I can see a script reference in pink. * I’ve just grabbed those offending scripts and plugged in the whole URL. For example, on my plugin, there is a dedicated box to have a script run ASYNC. So, I entered the full path. * [https://cdn.ampproject.org/v0.js](https://cdn.ampproject.org/v0.js) * Your plugin probably has some settings and different pages use different AMP scripts. I’ve pulled out 4 for my site so far. I don’t think minification is the issue. It wasn’t for me. * If you’re not sure the setting, I would contact the Velocity plugin author or test on a staging site if you have one. * [frenchomatic](https://wordpress.org/support/users/frenchomatic/) * (@frenchomatic) * [8 years, 1 month ago](https://wordpress.org/support/topic/disallowed-attribute-errors-on-random-posts/#post-10268983) * Try deactivating the velocity script and then test for AMP page validity using this * [https://search.google.com/test/amp](https://search.google.com/test/amp) * Thread Starter [Scott](https://wordpress.org/support/users/magius72/) * (@magius72) * [8 years, 1 month ago](https://wordpress.org/support/topic/disallowed-attribute-errors-on-random-posts/#post-10299934) * UPDATE: added exceptions for the Javascripts: * [https://cdn.ampproject.org/v0.js](https://cdn.ampproject.org/v0.js) [https://cdn.ampproject.org/v0/amp-form-latest.js](https://cdn.ampproject.org/v0/amp-form-latest.js) [https://cdn.ampproject.org/v0/amp-mustache-latest.js](https://cdn.ampproject.org/v0/amp-mustache-latest.js) * to the Fast Velocity Minify plugin and that seems to do the trick!
