As it writes, a problem with the indexes definitions of those tables. Please try a repair on the reported table and see if that helps. Have you activated a specific add-on lately or did you alter tables?
Have you tried the default theme? Does that work? Did you change the wp-content folder to something else?
jQuery is running in compatibility mode in WP. Instead of … $(document).ready(function() {} … use … jQuery(document).ready(function($) {}
In phpmyadmin search : SELECT * FROM wp_options WHERE option_name=”template” OR option_name=”stylesheet” OR option_name=”current_theme”; then : UPDATE wp_options SET option_value=”yourthemename” WHERE option_name=”template”; UPDATE wp_options SET option_value=”yourthemename” WHERE option_name=”stylesheet”; UPDATE wp_options SET option_value=”yourthemename” WHERE option_name=”current_theme”; or if you want to go back to default (presuming some default exists) SET option_value=”default” WHERE option_name=”template”; UPDATE wp_options SET option_value=”default” … Read more
I’m not seeing the original snippet from before so I’m not sure of the context anymore. The undefined index notice you are getting is telling you that $_POST[‘remove_field’] does not exist.

Redirects belong in a function hooked into wp_loaded to ensure they run before the request body is generated. You need something like the following in your functions.php file: function hook_wp_loaded_require_login() { $uri = ( isset( $_SERVER[‘REQUEST_URI’] ) ) ? … Read more
Reinstalling core should fix this issue. This is more than likely related to a botched update from 5.3 to 5.3.1.
