Support » Plugin: The Events Calendar » WP 5.7 Publishing Error PLUS Organizer/Venue Error

  • Resolved typecconsulting


    When trying to add a new event with the latest version of TEC and WP 5.7, I received the dreaded “Publishing failed. The response is not a valid JSON response.” error.

    I did read your known issues page where you did say there was an issue with this exact thing: – Unfortunately this still seems to be an issue with my client’s staging site.

    Adding to that weirdness, I also cannot seem to select any existing venues or organizers as they don’t appear in the dropdowns when I start typing the names in.

    This only seems to be an issue with WP 5.7 though as I’m not getting any errors when I try and publish an event on their production site which is on 5.6 still.

    I’m assuming this is the type of issue that y’all were worried about with the upgrade to 5.7?

    Hey @typecconsulting

    Thank you for reaching out.
    That specific version of the issue was fixed in a previous version of our plugin, but we some of our customers are still having a similar issue.

    Until an official fix is released, you might want to give the following extension a shot. Please make a backup before installing anything, of course.

    As for WP 5.7 it’s an important upgrade that will require testing everything (plugins, themes, etc..). I would recommend the following guide to help you iron out kinks

    Hey @geoffbel,

    Thanks for the quick response. Unfortunately I’ve uploaded the extension but it hasn’t fixed the saving issue. I’ll wait until the official release and hopefully that will fix things right up.

    Thanks for the heads up on 5.7. I’ve already installed that plugin on this particular site from looking at that doc, but will be cognizant of adding it to new developments moving forward.

    Hi @typecconsulting

    We are releasing a fix for this issue in our upcoming release!

    In the meantime, the following extension should resolve the issue:

    Let us know if that helps!

    Hi @typecconsulting,

    We are aware of a specific scenario where this issue won’t be fixed by the extension we shared. That is when using plain permalinks.

    We’ve already logged an internal bug report for this and we’ll let you know once we ship a fix for it.

    Are you using plain permalinks? If so, can you please confirm if using any other “pretty” permalinks option works for you?

    Thanks for your help and patience with this 🙂

    I just wanted to let you know that we’ve recently pushed an update that should resolve your issue regarding the block editor.

    Please update all your plugins and test to see if your issue is indeed resolved.

    If it’s not, let us know!

    Hey @highprrrr,

    So weirdly, it didn’t work at first and I was still getting the JSON error and it would create an Auto Draft, but then in Quick Edit I could then publish the Auto Draft, so I thought maybe it had to do with the permalinks as your colleague previously mentioned.

    However in looking, I wasn’t using plain permalinks so I didn’t think it was that, but I saved the permalinks nonetheless and lo and behold, the events starting saving from the editor screen again.

    So…it’s working! Yay! Thanks.

    Great! I’m glad it’s working.

    It’s not just you, randomly saving permalinks, even without changing anything has fixed a lot of WordPress issues. It’s one of the first things I recommend to people having unexplainable issues.

    Have a great week!

    Haha yep – it’s a cure all sometimes. Probably should have tried it earlier but now I know!
