Fix 1: Error Establishing a Database Connection
This error is not more complex, but it happens for a very simple reason WordPress can’t connect to its database. The database is like the brain of your site, storing all your content, users, and settings.
The problem is almost always a mismatch in credentials inside the wp-config.php file.
The Solution (The wp-config.php Check)
Access Your Files: You need to log into your hosting control panel (like cPanel or hPanel) or use the File Manager, or connect via an FTP program.
Locate the File: In the root folder of your website (usually public_html) and find the wp-config.php file.
Check the Credentials: Open the file and look for these four lines:
define( 'DB_NAME', 'wperrofixer-database_name' ); define( 'DB_USER', 'wperrorfixer_username' ); define( 'DB_PASSWORD', 'wperrorfixer_password' ); define( 'DB_HOST', 'localhost' );
Verify Them: Now, open your hosting control panel’s MySQL Databases section. Compare the Name, User, and Password defined in the file against the actual, live credentials shown in your cPanel. They must match perfectly, down to the capitalization.
Pro Tip: If the database password has been changed on the server side, you must update it in the wp-config.php file.
Still Broken? Contact Host: If the details are perfect, the issue might be with the database server itself (it could be overloaded or down). Contact your hosting support immediately.
Fix 2: There has been a critical error on this website.
This is the modern, user-friendly message for the infamous White Screen of Death (WSOD). It tells you that something in your site’s PHP code has crashed the whole system.
The Solution (Plugin and Theme Isolation)
This error is almost always caused by a plugin conflict or a bad theme update. You need to isolate the culprit.
Disable All Plugins: Since you can’t access your dashboard, so please use the File Manager (cPanel or hPanel) to navigate to: wp-contents/plugins.
Rename the plugins folder to something like plugins_old. This instantly deactivates everything.
Test the Site: Refresh your website.
If it loads (even messily): You know a plugin was the problem! Rename the folder back to plugins. Now, log into your dashboard, and reactivate plugins one by one, testing the site after each one. The moment the error returns, you’ve found the offender.
Check the Theme: If disabling the plugins didn’t work, go to wp-contents/themes.
Rename your active theme’s folder like Astra_old, GeneratePress_old, Divi_old or any others. WordPress will automatically fall back to a default theme (like a Twenty-Twenty theme).
If the site loads now, your theme is the issue.
Fix 3: Sorry, you are not allowed to access this page.
This typically happens when you can log in, but as soon as you try to access the Admin Dashboard, you get blocked. This is a permissions issue, often related to user roles or accidentally corrupted security files.
The Solution (The User Reset)
The easiest fix is to force WordPress to reset your user role to an Administrator using the database.
Access phpMyAdmin: Log into your hosting control panel and find phpMyAdmin (the tool for editing your database).
Find Your Users: In phpMyAdmin, click on your database name, and then click the table that ends with tablename_user (e.g. wp_users).
Find Your User ID: Find your username in the list and note the number in the first column (ID).
Reset Capabilities: Go back to the main list of tables and find the one that ends with _usermeta e.g., wp_usermeta). Click Search.
In the search form, set user_id to the ID number you just found.
Set meta_key to wp_capabilites.
Edit the result: Find the row for your user, click Edit, and change the value in the meta_value field to this exact string:
a:1:{s:13:"administrator";b:1;}Save and Test: Click Go to save the change. Clear your browser cache and try logging into your WordPress dashboard again.
Fix 4: Briefly unavailable for scheduled maintenance. Check back in a minute.
This friendly-looking message is actually a common glitch. It happens when WordPress fails to delete a temporary file after an update (either for a plugin, theme, or core).
The Solution (The .maintenance File Delete)
Access Your Files: Use your File Manager or FTP to access the root folder of your site (public_html).
Locate the File: Look for a file named .maintenance. It’s small, hidden, and usually the only file you see.
Delete It: Simply delete the .maintenance file.
Refresh: Clear your browser cache and refresh your site. The site should immediately spring back to life.
Fix 5: This site can’t be reached / 502, 503, 504 Errors
These “can’t be reached” and “gateway” errors are often not a WordPress problem at all, but a server problem.
The Solution (The Host Check)
These codes mean your browser tried to connect to your server, but the server either failed to respond quickly enough (Timeout) or was completely unavailable.
Clear Browser/DNS Cache: First, try clearing your browser cache or opening the site in a different browser. If it works there, the problem is local to your computer.
Check the Host Status: Immediately check your hosting provider’s status page or contact their support. High traffic, resource limits being hit, or general server issues are the most common causes. Your host is the only one who can fix server errors like 502, 503, and 504.
By systematically testing and eliminating these common causes, you can quickly and confidently resolve most WordPress errors without needing to hire a developer!
