Hi @dougrr,
Sorry to hear about the issues. In general, if a critical error was generated within the Hummingbird side, then deactivating Hummingbird should have resolved any issues that might have occurred due to it.
There isn’t any specific setting that Hummingbird would apply once the plugin is deactivated.
I renamed plugins to determine problem and site is live again with only Hummingbird deactivated but i still have no admin access
Could we know what exact error or message you notice when you try to access the admin dashboard? A screenshot would be helpful.
When optimizing, there was a warning regarding one of the optimizations and a possible redirect loop
Possible to copy-paste the message or share a screenshot of the error noticed?
If it’s still related to a critical error when accessing the dashboard, then would highly recommend enabling debug mode in order to have a better idea of what might have caused the issues.
To enable debug mode, open your wp-config.php file located in your root directory, and look for define(‘WP_DEBUG’, false);. Change it to:
define('WP_DEBUG', true);
In order to enable the error logging to a file on the server you need to add:
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
define( 'SCRIPT_DEBUG', true );
After making the above changes, please try to load the admin dashboard to replicate the issue. Once done the related errors will be saved to a debug.log log file inside the /wp-content/ directory.
You can find more details about debugging here:

Please share the debug log file in your next reply. You can share the debug file via Google Drive, Dropbox or any such cloud services in the next reply.
Please do let us know how that goes. Looking forward to your response.
Kind Regards,
