Error establishing a database connection
I have hosted a website on DigitalOcean.
I deleted unused media through a plugin “Media cleaner” (approximately 2K images).
But it deleted some used images.
Before doing this I have made a backup of only uploads through the Updraftplus plugin.
So I restored the backup.
Reassigned shortcodes in oxygen.
But something happened and now it is showing “Error establishing a database connection”
How to solve this? It’s urgent. Thank You!
