WordPress errors can be unnerving, especially when your site is down and the message on screen does not explain much.
Many common issues have familiar causes: a plugin conflict, a theme problem, a database setting, a failed update or a damaged configuration file.
Before you make changes, take a backup if you can. If you are not confident working with files or databases, ask your host or developer for help. Guessing your way through a broken WordPress site can make the repair harder.
Internal Server Error
An internal server error is a broad message. It usually means something has gone wrong between WordPress and the server, but the browser cannot show the exact cause.
Common things to check include:
- A damaged
.htaccessfile - A plugin or theme conflict
- PHP memory limits
- Recent changes to files, plugins or settings
If the problem started after installing a plugin, disable that plugin first. If it started after several changes, work backwards carefully rather than changing everything at once.
Error Establishing a Database Connection
This means WordPress cannot connect to its database.
Check the database name plus the username, password and host in wp-config.php. If those details are correct, the database server itself may be unavailable or the database user may not have the right permissions.
This error is often fixable, but it is worth being careful. The database contains your posts, pages, settings and users.
Briefly Unavailable for Scheduled Maintenance
During updates, WordPress briefly puts the site into maintenance mode. If an update is interrupted, the maintenance notice can get stuck.
The usual fix is to remove the .maintenance file from the website root directory. After that, check whether the original update completed properly. A stuck maintenance file may be the visible symptom, not the whole problem.
White Screen or Critical Error
A blank screen or critical error is commonly caused by a plugin, theme or PHP issue.
If you can access your hosting files, try temporarily renaming the plugins folder to disable plugins. If the site returns, rename the folder back and disable plugins one at a time until you find the cause.
A recent PHP version change can also expose problems in old plugins or themes. That does not mean the PHP version is wrong; it may mean the site has old code that finally needs attention.
Login or Password Reset Problems
If the password reset email does not arrive, check spam filtering and whether the site can send email properly.
For administrators with hosting access, passwords can sometimes be reset through the database, but this should be handled carefully. A safer route is to ask your host or developer for help if you are unsure.
Dashboard Styling Looks Broken
If the WordPress dashboard loads without styling, start with simple checks:
- Clear your browser cache
- Try a different browser
- Disable recently added plugins
- Check whether WordPress, themes and plugins are up to date
Security or caching plugins can sometimes interfere with admin files if configured too aggressively.
Lots of Spam
Comment and form spam is common on WordPress sites.
Use a reputable anti-spam tool, keep forms protected and avoid publishing plain email addresses where bots can scrape them. If you do not use comments, consider disabling them.
Fix the cause, not just the symptom
Getting the site back online is the first priority, but do not stop there.
Once the immediate issue is fixed, check what caused it. Update old software, remove unused plugins, review backups and consider whether your hosting setup is still suitable for the site.
