Error establishing a database connection (WordPress)

Hi there,

I’m having a really hard time figuring this out… My website shows up “Error establishing a database connection” on occasion. This happens about once a day. As soon as I reboot the droplet, the problem’s gone.

I’ve tried adding the following 2 lines in my wp-config file, as suggested on some other forums, but it didn’t work:

define(‘WP_MEMORY_LIMIT’, ‘64M’); define(‘WP_ALLOW_REPAIR’, true);

From what I read around the web, it seems that 512mb of RAM is perfectly fine for a wordpress multisite, if set correctly - though I’m having a hard time with a single (low content) site, without many plugins. I’ve also disabled/deleted the plugins that could potentially eat up a lot of memory, such as wp-backup.

If you have any suggestions for me, I’d be more than thankful! Please notice that I’m pretty new with all this, and as it’s my first time running VPS, I do have a bit hard time understanding how everything works, at the moment…
