Support » Plugin: Permalink Manager Lite » Get JS error on save in Gutenberg editor

  • Resolved Marcel Deglau



    I figured out an issue with the Gutenberg editor on WP version 5.3.2.

    When I do disable the plugin the “Save” issue does not apply. When I do enable the plugin, using the Gutenberg editor and click on save (for the post) in background it saves the post but didn’t process correctly because a javascript issue appear:

    edit-post.min.js?ver=3.8.6:6 Uncaught (in promise) TypeError: Failed to construct 'FormData': parameter 1 is not of type 'HTMLFormElement'.
        at edit-post.min.js?ver=3.8.6:6
        at (<anonymous>)
        at Array.REQUEST_META_BOX_UPDATES (edit-post.min.js?ver=3.8.6:6)
        at edit-post.min.js?ver=3.8.6:6
        at Object.dispatch (edit-post.min.js?ver=3.8.6:6)
        at edit-post.min.js?ver=3.8.6:6
        at data.min.js?ver=4.9.2:1
        at Array.forEach (<anonymous>)
        at o (data.min.js?ver=4.9.2:1)
        at data.min.js?ver=4.9.2:1

    Can you help in this case, why this may appear?

    Hi @marceldeglau,

    I am not able to reproduce this issue on my test server. I think that the issue is caused by some compatibility issue between Permalink Manager and other 3rd party plugin.

    Do you possibly have any staging environment, where I can debug this issue? If so, could you send me credentials to my email address: contact /at/

    Best regards,

    Marcel Deglau


    Hi @mbis,

    Thanks for the reply. I don’t know why but I was double checking the issue right now on my MacBook (2nd device) and the issue did no longer appear.

    I think there was some issue with cached resources. Anyway thank you very much for the fast reply and offer to help with!

    Stay Awesome and Kind regards,
