    Hey,

    I’m trying to export a course from a local WordPress/LearnDash installation, but I’m getting a 500 error message. I’m using Chrome.

    The browser error message says:

    “The website at http://[localName]/wp-admin/admin-post.php?action=export_course&course_id=39663&_wpnonce=070d727683 may be temporarily unavailable or may have been permanently moved to a new web address.”

    The browser console of Chrome says:

    GET http://[localName]/wp-admin/admin-post.php?action=export_course&course_id=39663&_wpnonce=070d727683 net::ERR_INVALID_RESPONSE 500 (Internal Server Error)

    The php error log shows this:
