 My site in development has some odd permission issues. chmod and chown all
 look great and able to upload images and make other saves. One particular
 issue that I can narrow down is the custom HTML widget saves great until
 the moment you add href inside an anchor.
 I have a [GIF here]https://keepbastropcountybeautiful.org/wp-
 content/uploads/href-poison.gif showing how Save works well and fast until
 the moment I place href=”” inside – then it freezes with spinning and it
 does not save. Looking at the logs, I do see a 403 returned on the admin-
 ajax.php . I see 403 returned in other scenarios such as post.php, but not
 all of the time. With the Custom HTML widget being so specific, what
 actions happen on save? I'm on 5.7.2 no plugins, 2021 theme
