I’m in a bit of a weird situation. Im using a wordpress site which has WooCommerce for purchases. It was working fine, and we recently decided to try this new plugin:
Which is for our wholesale customers. The issue is, about 1 in 10 times a wholesale user makes an order, the entire website goes down. It’s very strange, and it’s not a wordpress error, you just can’t reach the wordpress site at all.
I’ve tried contacting the plugin developer but they just say they’ve never seen it, said it’s another plugins issue and doesn’t really offer much more help.
Im kind of at a loss how to continue. I would love to collect some logs to provide to somehow help narrow down what is causing the issue. The server instance itself stays up, and I can ssh into it just fine. but trying to go the wordpress site online via the URL just shows an error “Site can’t be reached, and took too long to respond” (The error is from chrome not wordpress)
I’d prefer not to have to remove this plugin entirely and was just wondering if you had any ideas how I can narrow down what is happening. Once the site goes down I cant get it back up unless I restart the entire instance. I tried turning debug logging on, but nothing seems to be printed when it crashes.
I am also on the latest versions of all plugins.
Any advice is greatly appreciated .
actually just found something very interesting in the apache logs. any ideas

Disable all other plugins and start testing. Activating one at a time and trying again until you find out which one breaks the site.
You could also reach out to your host and see if it’s a resource limit on their end.
Have you checked the server logs, i.e., the PHP error log, Apache/Nginx error log?
I think you should copy the website.
Maybe use localwp? install the website there.
Try with duplicator or just copy the database and all files with FTP.
Then you can try and disable plugins.
Check your MySQL server for a stick query.
Looks like you’re using AWS Lightsail? How much RAM does your server have? IMHO Bitnami and Woocommerce need a 4GB server.
Edit: just saw your other comment about your server specs, you have 4GB so I don’t think your issue is memory-related.
