same error for me, i have 2 droplet with same wordpres site and details one crash and one work nice, WHY?

Hi @FidelM

Without seeing the database error log, then the best guess would be that you’re running out of RAM, so if you have a $5 droplet, then resize it to $10.

And if you are using CloudFlare’s offline-cache, then you need to setup some cache, since it visits every page within a very short time, which can easily drain the server for RAM.

Run the following command to show the last 40 lines of the database error log:

tail -40 /var/log/mysql/error.log
