Yoast internal linking meta box is not working
Blinking Yoast Logo or Analyze Content Button Remains
If you can see the metabox, but the Yoast logo keeps blinking or the analyze content button remains after completing the site-wide analysis, it might be possible that you have enabled a security setting that prevents the feature from working.
Below we have listed plugin settings reported by users. If you are not using one of these plugins, please run a conflict check to determine which plugin (security or otherwise) causes the blinking logo and report the issue to the premium support team.
Please disable the setting using the pathway below to filter long URL strings for the internal linking to work.
