Hello there, Can someone please help me, I always got this Error Establishing Database Connection on my website and it almost appears every day. I am on 512mb / 20GB disk Plan ( Droplet) and my traffics range is only 500-800 traffics daily. Can someone please tell me how to fix this issue? Almost getting this issue from the beginning I created my website. My website Plugins posted below:

Hi,
You’re getting that error because MySQL is crashing and so WordPress is no longer able to connect to it. MySQL and WordPress, especially with a lot of plugins installed, both require a lot of memory and a 512MB Droplet is not enough to handle those requirements.
I would recommend upgrading to a 1GB Droplet first—we have recently introduced new plans so you will be able to do that without any additional cost. But, you might want to also consider upgrading to a 2GB Droplet to make sure that both programs have some room to breathe.
Additionally, check out this tutorial on setting up Redis Caching. It is a bit old but the same instructions should work, though you might have to replace php5 with php7:
