 * hi guys,
 * so my ad sense ads are not shown anymore.
 * there is that error “the content filter does not exist” shown in the ad health.
 * i don’t know what do to, can you help me?
 * maybe this has something to do with the fact that I just got my verification 
   mail from adsense?
 * Best regards,

 * Hi Markus,
 * Thanks for reaching out.
 * The `the_content` filter is used by WordPress and many plugins to alter the post
   content before output. As it happens, some themes seem to forget about this or
   skip it intentionally. 404 pages don’t use `the_content` at all.
 * The most common mistake here is that themes use `get_the_content()` and not `
   the_content()` in order to output the content. If you are not sure about this,
   please ask your theme developer.
 * If you don’t want to place ads in the content or want to use Google Auto Ads 
   please just ignore this message and [proceed by placing the ads via shortcode or widget placement](https://wpadvancedads.com/place-adsense-ad-unit-manually/#Placing_the_ad).
 * Please let me know if you need anything else.
 * Best regards,
    Henning
