When I select “visit site” in my dashboard the only thing visible are those error messages frozen on the screen. My problem occurred when I modified code in my child themes function. php file. Since I modified, deleted the code, completely removed the file, reinstalled woo-commerce and WordPress but I’m still frozen out of my site. If I remove the woocommerce.php file or deactivate the woocommerce plugin my menu bar shows up. Any help would be appreciated.
