Support » Plugin: Campaign Monitor for WooCommerce » Uncaught error – Must supply a valid HTTP Basic Authorization header

  • When going through the connection process, after entering the client ID and client secret I am prompted for my Campaign Monitor credentials again. Then, upon returning to the WordPress admin, the page shows an uncaught error:

    Uncaught Error: Cannot use object of type stdClass as array in /path/to/wp-content/mu-plugins/campaign-monitor-for-woocommerce/views/admin/connect.php on line 110

    I am using the latest version of the plugin.

    Adding some debugging code to the location flagged in the error, I found that the object being returned is:

    stdClass Object ( [Code] => 50 [Message] => Must supply a valid HTTP Basic Authorization header )

    What can cause there not to be a valid authorisation header, and how can I fix it?

    Hi doubledesign,

    Sorry to hear of the trouble with this! It looks like there has been a hiccup during the initial connection process, as a first step, the best option would be to delete the plugin completely, reinstall and attempt to reconnect again.

    If you are still seeing issues, would it be possible to create a support case, so we can get your account details and check the logs for your Campaigb Monitor account in detail. You can create a support case here: by clicking Contact Support .

    Thank you!

    Thank you for the quick reply!

    I had tried clearing out all of the rows in wp_options related to the plugin to get the prompt again, but the issue still happens. As it’s being used on a multisite, I also tried on a different site, no luck. I will create a support case as I have some other questions about our use case that may be able to be answered at the same time. Thank you!
