Joomla 5 problems

1. Compatibility issues with third-party extensions: Some users have experienced problems with third-party extensions not being compatible with Joomla 5. This can cause errors and functionality issues[1].

2. Performance and loading problems: Some users have reported slow loading times, especially in the admin area. One user mentioned that the admin login screen builds very slowly and hangs when confronted by the Multi-Factor Authentication (MFA)[2].

3. Media section issues: There have been reports of nothing appearing in the media section after updating to Joomla 5[3].

4. Update detection problems: Some users have experienced issues with Joomla not being able to detect system and plugin updates in the Control Panel[3].

5. Update difficulties: Some users have reported problems updating Joomla, either automatically or manually[3].

6. Module creation issues: One user reported problems when trying to create a module in Joomla 5[4].

7. RSS feed image issues: A bug has been reported where if an intro image name (URL) contains a blank space, the img src in the RSS feed becomes invalid[5].

To address these issues, some suggested solutions include:

- Activating debug mode to identify incompatible extensions[1]
- Clearing site and browser caches[2]
- Rebuilding the update sites list[3]
- Trying different update methods, such as Upload & Update or changing the update channel[3]
- Checking internet connections and server settings[3]

It's important to note that not all users experience these problems, and some issues may be specific to certain configurations or environments. As with any major software update, it's recommended to backup your site before updating to Joomla 5 and test thoroughly in a staging environment if possible.
