Hello,
it seems there is an issue with your website, very likely caused by some plugin that does content processing.
Ad Inserter doesn’t get the content for processing (via the_content WP filter hook) so it can’t insert anything.
Try to disable other plugins to see which one caueses issues.
You can also try to lower Ad Inserter plugin priority for earlier processing, for example to 5:
