Unexpected Token In JSON

    Hi!

    I am seeing this error as well. Have noted it for the last week or so. It causes Gutenberg to hit admin-ajax.php an average of 25 attempts per edit page load.

    Uncaught SyntaxError: Unexpected token < in JSON at position 0
    at JSON.parse (<anonymous>)
    at Object.success (mfis-admin-block-editor-scripts.js?ver=5.3.2:57)
    at i (jquery.js:2)
    at Object.fireWith [as resolveWith] (jquery.js:2)
    at x (jquery.js:4)
    at XMLHttpRequest.c (jquery.js:4)

    I am not sure if this is worth mentioning but when I noticed the error initially, it was hitting admin-ajax.php upwards of 200+ attempts per edit page load. My first response was to disable and then re-enable the plugin. In this case, the caching might have been helping repeat the editor load. Unsure.

    General error from the console:

    TypeError: Cannot read property 'requestContent' of undefined

    Digging into this a bit more, I am seeing an average of 36 requests for “mfis_get_size_from_id” per reload (and then a few more for added measure).

    The json response I am seeing is:

    {"image_check":"pass"}

    The mfis_do_ajax_block_editor function seems to loop a lot when it is trying to figure out the image details. But I am guessing.

    Of course, I am not familiar with how many requests should be made on Gutenberg load.

    The server’s json response is what is expected by the plugin, so there shouldn’t be an issue there.

    Only thing I can think of to suggest is that you disable other plugins and try one of the default themes to rule out the problem being in your plugin/theme setup.
