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 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?
