Fatal Error after 4.1.1 upgrade

Please try again now – you should be able to see it.

Thanks

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?

Thanks – tried that and got the following error:

Parse error: syntax error, unexpected ‘;’, expecting T_PAAMAYIM_NEKUDOTAYIM in /var/www/wordpress/wp-content/themes/m-science_bak2/simple_fields_config.php on line 2

Still no access to admin

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

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(
                '

            return $output;

        }
