Hello @vafaifreddy,

We have a Support Tool that will gather relevant information for us to analyze your configuration and logs. Could you please execute it on the machine where the stack is running by following the steps described in the guide below?

Please note that you need to paste the code ID that is shown at the end.

Thank you !
just sent a message with the manual upload!

Hello @vafaifreddy,

I was checking the support output and it is almost empty. It is usually due to a lack of memory or storage. Could you please execute the following commands and share the output with us?

cd /opt/bitnami
free -m
df -h
df -ih

the site is now going down consistently.

Hi @vafaifreddy,

It seems the instance is using a lot of swap. Note that WordPress requires at least 700M.

You could try to increase your machine type if you face performance issues. This guide explains the process

Let me share with you our troubleshooting documentation:

We also have a guide to optimize Wordpress:

I upgraded my instance and it seems to be working ,

thank you !
