Keeping WordPress up to date is important for security, performance, and access to new features. However, every update introduces changes to the website’s environment, which means there is always a possibility of compatibility issues.
While most updates complete without problems, website owners should take precautions before updating.

Potential risks of updating WordPress
Plugin incompatibility
One of the most common issues after an update is plugin incompatibility.
This can occur when:
- a plugin has not been updated by its developer
- the plugin relies on outdated WordPress functions
- multiple plugins conflict after the update
In some cases, website functionality may be partially affected.
Theme incompatibility
Themes may also encounter compatibility problems after a WordPress update.
Possible issues include:
- broken layouts
- display errors
- missing functionality
- customization conflicts
This is more common with older or unsupported themes.
Database issues
Although uncommon, database-related problems can occur during major updates.
Examples include:
- incomplete database upgrades
- corrupted data structures
- errors caused by interrupted update processes
These issues can affect website functionality until repaired.
Website downtime
If an update fails or encounters compatibility issues, the website may become temporarily unavailable.
Possible symptoms include:
- error messages
- blank pages
- administrator login problems
- malfunctioning website features
How to reduce the risks
Create a backup
Before performing any update, create a complete backup of:
- website files
- database
- configuration settings
A backup allows you to restore the website if anything goes wrong.
Test updates first
Whenever possible, test updates in a staging or development environment before applying them to the live website.
This helps identify compatibility issues without affecting visitors.
Verify compatibility
Before updating, check whether:
- plugins support the new WordPress version
- themes are actively maintained
- critical extensions have recent updates available
Keep components updated
Regularly updating plugins and themes reduces the likelihood of major compatibility problems when updating WordPress itself.
Benefits of updating WordPress
Despite the risks, updates provide important advantages:
- security improvements
- bug fixes
- performance enhancements
- new features
- better compatibility with modern technologies
Running outdated versions of WordPress can expose a website to security vulnerabilities and stability issues.
Summary
Updating WordPress carries some risk, particularly regarding plugin, theme, and compatibility issues. However, these risks can be significantly reduced by creating backups, testing updates beforehand, and ensuring all website components are actively maintained. In most cases, the benefits of keeping WordPress updated outweigh the potential risks.
