    Hi @lukefinsaas,

    Looks like your system report was removed from the post. But you’re describing a problem that a lot of people come across. Almost every the time it is caused by the server configuration, usually mod_security or mod_rewrite. It is probably affecting the AJAX POST requests – either blocking or rewriting them.

    If you’re using a hosting provider and have no control over the config, you might have to contact them to fix this.

    Hi @lukefinsaas,

    We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
