WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: RSS feed does not validate., by Samuel Wood (Otto) @jaishree10 Your site still clearly has several plugins enabled. Yoast SEO, Google Tag Manager, W3 Total Cache, etc. Also, your theme is called “viral” so you’re not running the base theme either. When we ask you to disable all plugins, we actually mean *disable all plugins*. WordPress isn’t doing this to your feeds, one of your plugins is. Without turning them off, there’s no way to see what the base line is. Then you turn the plugins back on, one at a time, to see which one breaks it. If you’re not willing to debug the site and actually turn off the plugins to get that baseline, then nobody can actually help you. Reply To: RSS feed does not validate.
