WordPress PSA: disable “Glue for Yoast SEO & AMP” plugin

If you have a site using the AMP plugin in “Reader” (formerly “Classic”) mode – which is to say it uses some simple templates for rendering AMP pages – you should remove Glue for Yoast SEO & AMP:

– it is no longer necessary
– the code in glue-for-yoast-seo-amp/classes/frontend.php adds a duplicate inline CSS selector for

header.amp-wp-header

and

.amp-site-title a

. This means the default colour scheme will override colours you set in Appearance > AMP.

Disabling the plugin fixes this.

(Tested with AMP 1.5.5, WordPress 5.4.2)
