Generating an XML sitemap for your images is a daunting task, especially if you are using shortcodes to display your images.
- The first thing to try is to disable the execution of shortcodes in XML sitemaps of images with a hook (paste it to your functions.php file of your child theme / theme)
- Disable Image sitemap from SEO, XML – HTML sitemap settings page, General tab
My XML sitemap is blank
XSL issue
There may be a problem with the stylesheet associated with the XML sitemap. It may not be loading or has been altered via your theme or a third-party plugin.
Generally, by looking at the source code of the stylesheet, we can quickly find the culprit.
URL of the stylesheet: https://example.com/sitemaps_xsl.xsl
WP Debug
Or, if your index sitemap and / or sub-sitemaps are blank, including your source code, you have to enable the WP Debug feature to get the error. Once the debug is enabled, load again your XML sitemap. The error will appear in your debug.log file.
A URL is missing in my sitemap
Make sure you don’t have set your URL as noindex.
If you have set a custom canonical tag different from your permalink, it will be automatically excluded from the sitemap too to follow Google guidelines.
My XML sitemap still doesn’t work
