Issues with Templates After Updating to Joomla! V5.2.4 and Temporary Solution

After updating to Joomla! V5.2.4, many users have reported issues with templates using the Helix framework, particularly the disappearance of the header and menu. This issue is likely related to changes in the Joomla! update, which may have affected how template settings are saved and displayed. Fortunately, there is a temporary solution that can help restore header functionality until an official fix is released.

Solution

Follow these steps to restore the header:

Find the options.xml file
This file is usually located in your template directory, such as:
templates/[template-name] or in your custom template directory.

Edit the options.xml file

• Open the options.xml file in a text editor.
• Find all instances of type="checkbox" and check the default attribute.
• If the value is default="0", change it to default="" (an empty string).

Example Modification:
Original Code:

<field name="predefined_header" 
       type="checkbox"  
       helixgroup="header"  
       label="HELIX_ULTIMATE_PREDEFINED_HEADER"  
       description="HELIX_ULTIMATE_PREDEFINED_HEADER_DESC"  
       default="0" />

Modified Code:

<field name="predefined_header" 
       type="checkbox"  
       helixgroup="header"  
       label="HELIX_ULTIMATE_PREDEFINED_HEADER"  
       description="HELIX_ULTIMATE_PREDEFINED_HEADER_DESC"  
       default="" />

Check Template Settings
After modifying the file, go to the template settings and ensure that the predefined header is enabled.

Clear Cache
To make sure the changes take effect, clear Joomla!'s cache.

This temporary fix should restore the header functionality. Keep an eye on new updates from Joomla! and the Helix framework for a permanent solution.
