    (Spinoff thread as same error message appears to result from different problems)

    Recap:
    I can’t change any Jetpack settings on my self-hosted site anarchic-teapot.net, and the error is always

    Error updating settings. SyntaxError: Unexpected token < in JSON at position 0

    Theme: Mantra
    Active plugins:

    • 404page – your smart custom 404 error page
    • Akismet Anti-Spam
    • Cookie Law Info
    • Cryout Serious Theme Settings
    • Disqus Comment System
    • FD Footnotes
    • Jetpack by WordPress.com
    • List Categories
    • Redirection
    • Special Text Boxes
    • Wordfence Security
    • WP Edit
    • WP Super Cache
    • Yoast SEO

    All are the latest version.

    In addition to this, although Jetpack is connected to WordPress.com, if I try to access plugin management there I get data retrieval errors for users & plugins and it is impossible to update site settings (not even site name or description) for both of the self-hosted sites I run or help run, even though the other site doesn’t generate any errors if I change Jetpack settings directly from the backend.

    You advised me to do this:
    Open the dashboard page.
    Open your browser console
    Click on the Network tab
    Refresh the page.
    Try to change some of your Jetpack settings
    If you see any lines in red inside the browser console, click on them. A new panel should appear on the right.

    I followed your suggestion and got as far as clicking on the red line. Bingo!

    Thanks for all the details.

    Could you review your Wordfence Security settings, and make sure you didn’t completely disable the WP REST API there? Jetpack does indeed rely on the WP REST API to activate and deactivate features, or to change Jetpack settings in your dashboard.

    Let me know how it goes.

    I had a look, and can’t find anything like that. WF has a couple of functions that block specific features, e.g. accessing users’ names, but disabling them made no difference.

    Could you try to deactivate the plugin altogether? If you still experience issues, we’ll know they’re not linked to WordFence.

    Thanks!

    Ahead of you on that one. Unfortunately it changed nothing.

    I get that unexpected token error as well and I’ve disabled all other plugins.

    @estevancarlos Could you please start your own thread, as per the Forum Welcome?
    https://wordpress.org/support/plugin/jetpack#new-post

    @anarchic_teapot Can you please go ahead and try disabling all of your plugins except Jetpack. Then try testing again to see if the issue persists. If that resolves your issue, you can find what was causing it by enabling each plugin one by one while continuing to test.

    Let me know how things go.

    The problem persists.

    I am convinced the problem lies with Jetpack. Incidentally, when I try the centralised site management interface on WordPress.org, it says my version of Jetpack is out of date (it isn’t).

    In fact, I even get an error with wordpress.com hosted sites on that same interface, e.g.:

    There was an error retrieving users

    Jetpack is the problem. It and Akhismet are all I have active on that blog.

    At this point, I’d like to run some more tests with you on your site to try to figure out what’s happening. Could you contact us via this contact form and mention this thread?

    Er… that’s not a contact form, it’s a search form.
