after installation of the template, I have some errors. See screenshots for frontend end backend error message.
How can I fix it?
It's compatibility issue with PHP 8.2 version and we fixed this issue in the latest version of GK Photo template.
You can go to: https://www.joomlart.com/member/downloads/gavick/joomla-templates/photo and download the latest version 4.2 of this template and install into your site.
Remember to BACKUP your site first.
