With the advent of PHP 7, many Joomla 2.5 website owners are trying to switch their web hosting to PHP 7. While PHP 7 is generally faster than PHP 5.x, it is unfortunately not compatible with Joomla 2.5. This incompatibility manifests as issues with category display restrictions and the disappearance of field translations in the administration panel. If Joomla 2.5 owners have not made extensive changes in the administration, PHP can be switched back to version 5.x, and everything should be restored to normal.opět spraví.
