1. Check and Update Your Database Login Credentials
- Verify Database Login Information in wp-config.php
Thewp-config.phpfile contains essential login information that WordPress uses to connect to the database. If the database name, username, password, or hostname is incorrect, WordPress will not be able to access the database, leading to this error. Openwp-config.phpusing an FTP client and double-check these entries to ensure accuracy. - Correct Typographical Errors
Simple typographical errors inwp-config.phpcan cause connection issues. After openingwp-config.php, carefully examine each line for spelling or syntax mistakes. Typing even one character incorrectly can disrupt the connection, so ensure everything is spelled correctly and formatted as needed. - Test Database Credentials Using cPanel or phpMyAdmin
If you have cPanel access, try logging into phpMyAdmin using the same credentials to confirm they’re correct. This method allows you to test your connection outside of WordPress, which can help isolate whether the problem lies with WordPress settings or the server itself.
2. Repair a Corrupted Database
- Enable Database Repair in wp-config.php
WordPress has a built-in database repair feature. You can enable this by addingdefine('WP_ALLOW_REPAIR', true);in yourwp-config.phpfile. This command allows you to access the repair page by visitinghttp://yoursite.com/wp-admin/maint/repair.php. This page lets you repair or optimize the database, which may fix any corruption issues. - Run the Repair Option and Check Results
After accessing the repair page, run the “Repair Database” option. WordPress will attempt to fix any issues in the database tables. Once complete, test your site to see if the error persists. Remember to remove the repair code fromwp-config.phpafterward to ensure security.
3. Resolve Hosting and Server Issues
- Contact Your Hosting Provider
Hosting providers can experience temporary server issues, so reach out to your hosting support to inquire if there’s ongoing maintenance or server downtime. If you need a more stable hosting environment, consider switching to WP Engine, known for high reliability and excellent customer support. - Check for Heavy Server Load or Memory Limits
A heavy server load can limit access to your site’s database. Ask your hosting provider if your site is exceeding resource limits and request an increase if necessary. Alternatively, upgrading to a plan like HostSquad’s Life Time Unlimited Hosting can help alleviate memory restrictions.

Cleaning up unnecessary data, like deleted posts, unused plugins, and outdated comments, can reduce database load and optimize performance. Use plugins like WP-Optimize or WP-Sweep to clean your database. - Implement Database Caching
Caching reduces database calls by serving stored pages directly to users. Plugins like W3 Total Cache or WP Rocket offer database caching, which reduces the server load and minimizes connection issues.
5. Change Hosting Providers (If Needed)
- Choose a More Reliable Hosting Solution
If your hosting provider is the root cause of persistent issues, consider upgrading to a reliable host like Namecheap or WP Engine. These platforms offer robust server environments and support for WordPress-specific issues.

Keeping regular backups of your database can help you quickly restore your site in the event of database corruption or errors. Use plugins like UpdraftPlus or BackupBuddy to automate daily or weekly backups. - Limit Plugins and Optimize Code
