It might be upsetting to run across an issue that prohibits people from visiting your website as a website owner. A common problem that WordPress users run into is the "Error Establishing a Database Connection" error. When WordPress is unable to connect to the database that houses all of the data on your website, this error occurs. How to correct this issue and get your website back online will be covered in this post.
Step 1: Verify Your Credentials for the Database
Verify your database credentials as the first step in correcting this problem. Locate the database settings section in the wp-config.php file of your website to take this action. Make sure that the database name, username, and password are typed accurately. You must edit them if any of these details are untrue.
Step 2: Verify Your Database Server
The next step is to confirm that your database server is operational. Entering your hosting account and going to the database section will allow you to verify this. Whether or not your database server is operating, get it going. Get help from your hosting company if you're not sure how to do it.
Step 3: Fix Your Database
If your database server is operating normally, but you are still getting the error, your database may need to be repaired. Enter the cPanel of your website or enter your database using a program like phpMyAdmin to accomplish this. Choose your database, then "Check All" tables from the menu that appears. After that, choose "Repair Table," and the utility will fix any corrupted tables.
Step 4: Increase the PHP Memory Allotment
The PHP memory limit is an additional potential root cause of the problem. The code shown below should be added to your wp-config.php file to raise this limit:
determine ('WP_MEMORY_LIMIT', '256M');
This code will raise the RAM ceiling to 256 MB, which should be sufficient to resolve the issue. If it doesn't help, try raising the cap to 512 MB or even 1 GB.
Step 5: Speak with your hosting company.
The issue can be with your hosting company if none of the aforementioned measures resolve it. Make contact with them and let them know about your situation. They could know how to find the issue and solve it for you.
The "Error Establishing a Database Connection" problem might be annoying, but it can be fixed. You can easily get your website back up by following the procedures above. To prevent data loss, always create a backup of your website before making any changes to your database.
