    I get ‘A post type mismatch has been detected.’ when I try to post or save a draft

    I am running WordPress 5.3.2 with the Scaffold theme.

    My site was working, but stopped working when I upgraded to 5.3.2

    I also upgraded the Gutenberg plugin.

    I have disabled all my plugins and that didn’t change anything.

    Help! I can’t post to my blog.

  • Hi there!

    What’s the address of your site? From what you’re saying, it looks that it is not hosted with WordPress.com. It is a site using the open-source WordPress software (from WordPress.org) but hosted elsewhere.

    Because WordPress.com and WordPress.org are two entirely separate entities, we cannot access files or data for sites that are hosted elsewhere, so WordPress.com staff can only assist with sites that are hosted on our servers. You can read more about the differences between WordPress.org software and WordPress.com here:

    WordPress.com vs. WordPress.org

    You can look for help at the community forums here: https://wordpress.org/support/forums/

    http://wordpress.org/support/ is also a great resource for sites using the open-source WordPress.org software.
