Between Smush Pro and Hummingbird, the two plugins brought down the performance of our site and started exhausting worker threads on our server.

    Hello B+F Accounts Payable,

    I hope you're find today and thank you for your question!

    These notices in the log suggest that the Hummingibird plugin is not able to write to its own log. Most likely the folder where it does store the log doesn't exist or is not writable so please check the permissions of the "wphb-logs" folder inside "wp-content". It should be writable for the plugin.

    I have also tried to check your site but unfortunately the support access, although it seems to be enabled, didn't work for me. This happens sometimes but luckily the solution is usually simple: please go to the "WPMU DEV -> Support" page and revoke and re-grant access from there, then let me know here.

    Best regards,

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
