Error Establishing A Database Connection WordPress Hosting Ubuntu Server – Today I edited a client’s WordPress page using a WordPress extension. I implemented security rules for the case.
After that, both clients’ WordPress pages had a “base-to-base connection establishment” error. Pages are not edited by me.

I can only contact Plesk support if I have purchased a Plesk license directly from Plesk. My hosting provider claims that I am the server manager and does not provide any support.

Do you see WordPress pages when you open them in a browser? In that case, click the “Refresh” icon in the WordPress Toolkit title bar to reload the page settings in the WordPress Toolkit.
Then you have not set the correct database user or password. Look in the relevant site’s wp-config.php and create a username/password combination with the same values for the database mentioned there. Check if the database name is correct. If not, change the wp-config.php file to the appropriate database. It doesn’t matter whether you adapt the database, user and password content of wp-config.php or the content of wp-config.php to an existing database, user and password. Works both ways. If you are getting “Error establishing database connection”, it means that the access credentials (or possibly the database name) are incorrect. Admit it, this error message looks pretty serious. No layout, no familiar WordPress site elements, just text:
We know you’re a little scared right now, but let’s reassure you that this problem can be fixed and any permanent damage can be avoided. In fact, the error when establishing a database connection is very common.

WordPress uses two main technologies to provide all its incredible capabilities: PHP and MySQL.
Together, WordPress uses PHP commands to connect to the MySQL database, get the necessary information, and then display everything on the screen.
This is the weakness of the game. The error occurs when, for whatever reason, WordPress cannot access database information through PHP commands. When this happens, WordPress basically doesn’t know what to do next, so the only thing it can say is “Error establishing database connection”.
That being said, there can be a few reasons why an error might occur. Some of the most common:

If your website was working a minute (or a day) ago and now it’s not, then it’s safe to assume the fault may be on your web host’s end.
Start by contacting that live chat, say you’re having an “error establishing database connection” (paste the phrase) and ask:

In most cases, if you tell them what kind of error you’re having, they’ll tell you exactly what’s causing it or fix it for you.
Most importantly, they will let you know if your database is healthy and if there is any suspicious activity on the server.
If the failure is not on their end (the server is working and there are no traffic spikes), and they do not want to help you, proceed to step 2:
For example, maybe you updated a plugin or theme and everything crashed? Maybe you connected the site to an external service? Maybe you edited some files manually?

If any of the above rings a bell, you’re probably guilty. If you haven’t done this, skip this step.
To connect, you need the login and password for your FTP account. If you don’t know what/where these are, the easiest way to get them is to look for them in the first posts you sign up with your web host. Alternatively, you can ask your live chat support representative to provide these details.
With these, connect to the server and navigate to the WordPress root folder. It’s usually called “public_html” or “www” or you might be there when you set up an FTP connection.
The rule is that if you see subfolders like “wp-content” and “wp-admin”, you are in the WordPress root. Example:

If not, now you know that some plugin caused it. Return to FTP, rename the folder “Plugins”. Go there and change the plugin folder names one by one. The easiest way to do this is to add an underscore at the end: “_”
Return to your site to see when the error starts or goes away. After narrowing it down to a specific plugin, you’ve found the person causing the problem. Either delete or go online to see if a solution is documented.
A WordPress database is a very complex thing, and there are many small gears that must be working perfectly to avoid problems. Sometimes something goes out of place and that’s when you see an error while establishing a database connection.
It’s actually quite simple. First, connect to your site via FTP again. Go to the WordPress root and download the “wp-config.php” file to your desktop.

Click a button. After the automatic repair is finished, go back to your site and see if the error is still there.
If there are no errors, great! But you still need to restore your “wp-config.php” file to its previous state. Remove that new line you just added and upload the file again.
As we mentioned, WordPress uses a unique username and password to connect to the database. Normally, these access credentials themselves do not change. However, you may experience some strange scenarios after changing your site files, hosting environment, or something else. In other words, even though it shouldn’t be, access credentials sometimes change. And with bad access credentials – “Error establishing database connection” occurs!
They store all the details that WordPress needs to connect to the database. If any of these are false, no connection will be established.

Note that this is a manual way to fix the problem, but it honestly requires a lot of steps and can be really confusing depending on the web host you use and the interface they use. In other words, everything we can say will only apply to a small range of users who are still using our same host, so we have a very universal solution for you.
Take those four lines from the “wp-config.php” file, copy them to the clipboard, contact your web host’s support again, paste those lines into the chat window and ask if the details are correct so you can connect. in your database.
The representative will check everything and get back to you with some feedback. In most cases, they will give you the correct details if something has changed.
All you need to do is grab the new credentials and place them in your “wp-config.php” file where the old ones were.

At this stage, you can go back to your site and see if the error is resolved.
As we mentioned earlier, core WordPress files can get corrupted due to various reasons. Maybe there was an attempt to hack your website, maybe you accidentally changed some files, maybe a bad plugin did it.
However, you can restore the original WordPress default files. The easiest way to do this is to download a clean version of WordPress from WordPress.org and copy it over to what you have now.
Go here and download the latest package to your desktop. Browse to the downloaded unzipped archive and delete the “wp-content” folder.

Next, connect to your site via FTP, navigate to the main WordPress root, upload your new WordPress files. Overwrite all previous files.
This is the type of repair of last resort. If that doesn’t help, you have no choice but to go back to your web host’s helpline, tell them everything you did, and ask for help. At this stage, you’ve basically exhausted everything you can do to fix the problem yourself and it’s the host’s turn to fix it. You’re paying your hosting bills, right?
