Error Establishing a Database Connection Fix
This error means exactly what it says: WordPress cannot reach its database. The cause is usually one of four things, and they are quick to distinguish once you know where to look.

Symptoms I see with this.
If any of these describe what you're looking at, this is the right fix. If you're not sure, describe it and I'll point you at the right one.
- "Error establishing a database connection" on every page
- The error appears and disappears intermittently
- It started after a host migration or a password change
- wp-admin gives the same error
What usually causes it.
In roughly the order I check them. Knowing the likely causes is what makes a fix fast rather than exploratory.
Wrong credentials in wp-config.php
Almost always the cause after a migration or a rotated password. The database name, user, password or host in wp-config no longer matches reality.
Database server down or at connection limit
Intermittent versions of this error usually mean the MySQL server is hitting max_connections or being restarted under load. That is a capacity problem, not a configuration one.
Corrupted database tables
A crash or an unclean shutdown can corrupt tables. Repair usually resolves it, and it is worth understanding why it crashed.
Wrong database host
Some hosts use a dedicated database hostname rather than localhost. Getting this wrong produces exactly this error and is a one-line fix.
What the job includes.
- Cause identified rather than guessed at
- Credentials and database host corrected
- Table repair and integrity check if corruption is present
- Connection limit and resource check if the error is intermittent
- Verification that wp-admin and the front end both work
- 14-day correction guarantee
Questions, answered.
Is my data lost?
Very unlikely. This is a connection problem, not a data problem. Even where tables are corrupted, repair usually recovers everything.
It keeps coming back. Why?
Intermittent failures point at resource limits rather than configuration — the database server is being overwhelmed or restarted. That needs a capacity conversation with your host, and I will give you the specific evidence to have it.
Can you fix it if I only have cPanel access?
Yes. cPanel or any file manager plus database access is enough.
