Well, there aren’t any errors there. Those warnings are a separate issue. * What plugins do you have active? * Thread Starter [Raul Craveiro](https://wordpress.org/support/users/craveiroraul/) * (@craveiroraul) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-when-validating-2/#post-12569630) * Autoptimize, Contact Form 7, EWWW Image Optimizer, Ezoic Integration, Yoast SEO, Glue for Yoast SEO & AMP, Redirection, WP Super Cache and the AMP plugin. * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-when-validating-2/#post-12569646) * Ok, could you please try deactivating Autoptimize and retrying to validate? * Thread Starter [Raul Craveiro](https://wordpress.org/support/users/craveiroraul/) * (@craveiroraul) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-when-validating-2/#post-12569648) * Got the same error. * But I deactivated the Ezoic Integration plugin and It worked. * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [6 years, 2 months ago](https://wordpress.org/support/topic/error-when-validating-2/#post-12595722) * I suggest opening a support topic on the Ezoic Integration [support forum](https://wordpress.org/support/plugin/ezoic-integration/). There’s some compatibility problem, most likely due to an output buffering conflict. I can see they are starting output buffering extremely early, at `plugins_loaded` action. The AMP plugin starts buffering at the `template_redirect` action (see [source](https://github.com/ampproject/amp-wp/blob/1094ea03bd5dc92889405a47a8c41de1a88908de/includes/class-amp-theme-support.php#L1091-L1096)) which we’ve determined is the earliest that this should be done. I’m happy to help them troubleshoot. Then again, I’m not familiar with Ezoic, so it may be that their service is fundamentally not AMP-compatible in the first place (e. g. needing to inject custom scripts into the page which aren’t AMP-compatible).
