Hello @savyk9
I hope you’re well today!
GZIP compression is a server-side thing and Hummingbird only helps you control it if it’s allowed by server configuration. If you can’t disable it, it usually means that the server is configured in a way that’s not allowing it.
However, GZIP compression isn’t something that could cause issues like those that you described.
Most likely, these issues (white screen, adding to cart not working etc) is a matter of some sort of a plugin conflict or resource issues.
If you disable Hummingbird plugin entirely, does the problem go away completely?
If yes, I’d suggest to start with checking outcome of WordPress debugging. You can enable it by adding following lines to the “wp-config.php” file of your site, right above the “/* That’s all, stop editing */” line:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false);
Once they are there, enable Hummingbird again, try adding something to the cart, try searching for new plugins – basically, trigger all the issues you think are related.
After that, look into the “/wp-content/” folder of your WordPress installation and you should see there a “debug.log” file. Take a look inside please and see if it shows any errors/warnings (there are dates included so check around the time you were testing it).
If there are any, let us know about them here.
If this doesn’t give any errors, please perform a full conflict test:
– temporarily switch site to “Twenty Twenty” theme
– disable all the plugins
– enable Hummingbird back
– if no issues are happening start enabling plugins (and theme) one by one, after each one checking if any of the issues come back;
The last enabled plugin (or the theme) right before issues start to happen again would be the most likely culprit and we’d investigate it further so let us know about test result too, please.
Kind regards,
Adam
