Thank you for trying to help.

I inherited this site and have little to no knowledge of PHP so excuse me if I sound dumb.

I have spotted an add-on plugin wirtten by the site author, could this be conflicting with ‘Simple Fields’?

<?php
/*
Plugin Name: Button Field
Description: Add on for simple fields plugin
Version: 1.0
Author: Rafael G. Lepper
*/
add_action("plugins_loaded", "init_simple_fields_field_button");

function init_simple_fields_field_button() {

    class simple_fields_field_button extends simple_fields_field {

        public $key = "buttonfield", $name = "Button field";

        function __construct() {
            parent::__construct();
        }
                /**
         * Output fields and stuff on post edit page
         * This is the output a regular user will see
         */
        function options_output($existing_vals) {
            return ;
        }

        function edit_output($saved_values, $options) {

            // name tex. date: simple_fields_fieldgroups[3][1][new0]
            // name denna: simple_fields_fieldgroups[3][2][new0][option1]
            // alltså ett steg till = bra för vi kan lagra fler saker med mindre problem. hej hopp.
            $output = "";
            $output .= sprintf(
                '
                    <label for="%2$s">Button text</label>
                    <input type="text" placeholder="Button text" name="%1$s" id="%2$s" value="%3$s"><br>
                    <label for="%5$s">Button link</label>
                    <input type="text" placeholder="Button link" name="%4$s" id="%5$s" value="%6$s">
                ',
                $this->get_options_name("text"),
                $this->get_options_id("text"),
                esc_attr(@$saved_values["text"]),
                $this->get_options_name("link"),
                $this->get_options_id("link"),
                esc_attr(@$saved_values["link"])
            );

            return $output;

        }

        /**
         * Before the values are returned
         */
        function return_values($values) {
            foreach ($values as &$one_field) {
                foreach ($one_field as $one_field_key => &$one_field_value) {
                    if ($one_field_key == "text") {
                        $one_field_value = $one_field_value . "";
                    }
                }
            }
            return $values;
        }

    }

    simple_fields::register_field_type("simple_fields_field_button");

}

I can’t see admin on the testwww – it has white screen too.

Shall I try to restore and upgrade again – making sure plugin is active?

Can you see this: Fatal error: Call to undefined function simple_fields_register_field_group() in /var/www/wordpress/wp-content/themes/m-science_bak2/simple_fields_config.php on line 39

or nothing at all?

Yes
