WordPress Admin Connectivity Issues

  • Hello,

    One of our international clients is having several connection issues with the WordPress admin panel and ACF. We are however unable to reproduce any of these issues ourselves, on any Browser or OS.

    1. WordPress admin panel losing connection.

    When editing posts the admin panel loses connection and is presented with this error: (

    2. ACF Post Object drop downs

    All ACF Post Object drop-downs fail to load content. (

    3. Unable to upload images.

    When the client tries to upload images they are presented with the following error: “An error occurred in the upload. Please try again later.”

    4. On the front-end only SVG icons fail to load in Google Chrome.

    Connected to this are a myriad of smaller issues with the saving of posts that we believe are related to the larger issues outlined above.

    The website is hosted on a Digital Ocean droplet, runs PHP 7.0 on NGINX and is up to date with the latest WordPress and ACF PRO updates.

    We would be very grateful if someone could shine some light on these issues.

    Thank you very much for your help.



  • The item under #1 suggests to me that the connection issue is on the client end and they are experiencing internet connectivity issues that are unrelated to the server. For example, if I’m editing a page and I unplug my network cable I get the same error.

  • Hi John,

    Thank you very much for your reply!

    For a while that was our thinking too.

    However, I accidentally left out a detail that raises some doubts. The ACF AJAX fields do not work at all. They always return ‘Loading failed’. Even when they are able to load the whole admin panel and front-end without trouble. Network connectivity aside, there must be something going on.



  • The AJAX fields can field to load if there is a JavaScript error or there is a PHP error during the AJAX request. You need to look for JavaScript errors and turn on debugging and logging and check the error log to see if there are any php errors during the request. If both of these are negative then I’d go back to the internet connectivity assumption, especially if the site works fine for me and only breaks for the client.

  • Hi John,

    Thank you for the insight. We will try more debugging to see if we are missing errors. Otherwise we’ll stick with the connectivity.

    Thanks for helping out!
