Solved, after updating PHP to latest version
My version is 4.2.10 and the website is https://photo.enivid.eu/
I also tried to reinstall Redux but still have the same issue. Everything else is also up to date.
Same here I get these errors after the latest update:
Warning: Declaration of Redux_Typography::output($style = '') should be compatible with Redux_Field::output(string $style = '') in /home/enividn/photo.enivid.eu/wp-content/plugins/redux-framework/redux-core/inc/fields/typography/class-redux-typography.php on line 18
Warning: Declaration of Redux_Color::output($style = '') should be compatible with Redux_Field::output(string $style = '') in /home/enividn/photo.enivid.eu/wp-content/plugins/redux-framework/redux-core/inc/fields/color/class-redux-color.php on line 20
