    I have been using this plugin for months…starting today in both my prod and test instances I get the following when attempting to approve/deny users.

    I tried deactivating/re-activating…that did not clear the issue.

    ‘https://mysite.com/wp-admin/users.php?action=approve&user=35&_wpnonce=4ce4fe07ad

    Interesting development. I restored a copy of the site from the production HostGator VPS to a different hosting providers VPS on my dev VPS and the issue is not happening on my dev VPS.

    This error was not happening until today on prod VPS…so what should I be talking to HostGator support about with regards to config changes on the server that would cause this?

    So HG escalated issue to their sys admin and their response is below.

    This does not explain why all of a sudden the plugin is not working when I have been using the plugin for 90+ days and it was working the WP Core 4.3 for nearly 3 weeks…with the issue just happening in the past few days.

    This also does not explain why when I do a clone backup using Duplicator and restore it on another VPS that is not hosted by HG the plugin works just fine.

    However, I do think HG’s response warrants review by the plugin developer:

    Turning on WordPress debug mode,shows a number of other errors. When I enabled WordPress debugging mode, the site appears with these errors:

    Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0! Use

    __construct()

    instead. in /home/mysite/public_html/wp-includes/functions.php on line 3457

    Warning: Cannot modify header information – headers already sent by (output started at /home/mysite/public_html/wp-includes/functions.php:3457) in /home/mysite/public_html/wp-includes/pluggable.php on line 1207

    This points to an incompatible plugin. You’ll want to make sure all your plugins are compatible with WordPress 4.3. Looking at https://ww.wp.xz.cn/plugins/new-user-approve/faq/ , it does not list 4.3 as being compatible, though the support forums don’t necessarily suggest it’s not.

    When I grep the contents of all the files on the account, I discover the following:

    root@tao [/home/mysite/public_html]# grep -R set_html_content_type
    wp-content/plugins/new-user-approve/new-user-approve.php: add_filter( ‘wp_mail_content_type’, ‘set_html_content_type’ );
    wp-content/plugins/new-user-approve/new-user-approve.php: remove_filter( ‘wp_mail_content_type’, ‘set_html_content_type’ );
    wp-content/plugins/new-user-approve/new-user-approve.php: public function set_html_content_type() {

    The error that you’ve reported is being caused by the new-user-approve plugin as it’s using some outdated function.

    So I paid a developer to fix this code. Please add and release an update.

    The current version of the plugin does not fail on all server configurations (which caused a lot of time wasted troubleshooting!).

    But please fix this so others don’t waste time and money!

    Issue: Function was being called before declaring it.

    File Changed:
    new-user-approve/new-user-approve.php

    Removed “public” in front of the function:

    Before:

    public function set_html_content_type() {
    return ‘text/html’;
    }

    After:

    function set_html_content_type() {
    return ‘text/html’;
    }
