Hi @martinedens I don’t think our plugin is adding the title and alt text to the feed, and there’s an extra / in the IMG as well. I would try deactivating other plugins, a few at a time, and check the raw feed after each time, to see if it goes away. Once it does, reactivate those plugins one at a time, checking the feed each time, and see which one causes it to be added back.
The other more advanced method is to use SSH (you’ll need be familiar with SSH and have SSH access), and use the grep command to find code relating to the RSS feed, ‘the_excerpt_rss’ is one good way:
cd wp-content/plugins/
grep -r 'the_excerpt_rss' *
For my site as an example, it displays:
# grep -r 'the_excerpt_rss' *
featured-images-for-rss-feeds/featured_images_in_rss.php: 'the_excerpt_rss',
featured-images-for-rss-feeds-premium/includes/premium/premium.php:add_filter( 'the_excerpt_rss', 'firss_insert_ads', 15 );
featured-images-for-rss-feeds-premium/includes/premium/premium.php:add_filter( 'the_excerpt_rss', 'firss_featured_images_in_rss_first_image', 1001, 1 );
featured-images-for-rss-feeds-premium/featured_images_in_rss.php: 'the_excerpt_rss',
feedzy-rss-feeds/includes/feedzy-rss-feeds-feed-tweaks.php:add_filter( 'the_excerpt_rss', 'feedzy_insert_thumbnail' );
wordpress-seo/src/integrations/front-end/rss-footer-embed.php: \add_filter( 'the_excerpt_rss', [ $this, 'embed_rssfooter_excerpt' ] );
wp-piwik/classes/WP_Piwik.php: add_filter ( 'the_excerpt_rss', array (
From that result, I see that plugins with these folder names have code affecting the RSS feed:
featured-images-for-rss-feeds
featured-images-for-rss-feeds-premium
feedzy-rss-feeds
wordpress-seo
wp-piwik
And I can narrow down which one is causing issues or conflicting with other plugins.
Let me know if you need help finding the plugn? It may also be your theme, or a plugin that adds title tags to all images, and is affecting the feed as well.
