warning message when registering a new site

I am getting a warning message on the front end of my sub-site when trying to register a new site.

Warning: call_user_func() expects parameter 1 to be a valid callback, class 'ProSites_Module_BulkUpgrades' does not have a method 'render_gateway' in /home/ecyp/public_html/wp-content/plugins/pro-sites/pro-sites-files/lib/ProSites/View/Front/Gateway.php on line 136

    Hi Thomas,

    Thanks for posting on the forum.

    Could you please share the screenshot of the page where you are getting this warning message?

    I tried to confirm it on your site but i couldn't because the registration is disabled on your site.

    I tried to reproduce it on my test site using latest version of Pro Sites plugin but i didn't get the warning message.

    Would you mind if I logged in to your site and did some troubleshooting? This might help get to the bottom of this faster. If this is ok, just grant me temporary admin access to your site by clicking "Grant Access" button in the WPMU DEV Dashboard Settings as described on the following page and reply on this thread after granting it?


    Kind Regards,
    Vinod Dalvi

    Hello @Thomas

    I hope you are well today.

    I have just tried to modify your 'test' site and worked fine for me and I got no error. Maybe I am looking at wrong page?

    Would you please post a full page screenshot of the page you got the error? Also a step by step procedure would be very helpful. I mean, when you say create a site do you mean create from admin end? As I see you have registration disabled. Do you modify from the admin end, just extend or change the level?

    Please let us know.
