Problems with incompatible extensions in Joomla 3
One of the most frequent issues in Joomla 3 is the use of incompatible extensions. Many administrators install outdated or unverified modules, plugins or components, only to find their site broken, showing white screens or error messages.
Why incompatible extensions are dangerous
An extension interacts with the Joomla core, and if not updated or coded properly, it can conflict with other plugins or the PHP version on the server. In some cases, it also introduces serious security risks, opening doors for hackers.
How to prevent these issues
Always check extension compatibility, update history and reviews before installing. Make regular backups to restore your site in case of problems.
👉 If your site is blocked or slowed down by a faulty extension, don’t make random attempts: contact me for help. I can quickly identify the cause and restore full functionality.
