Duplicate admin page went blank

Hi there,

The admin page for duplicating a site went blank after I had made some other changes to other things in the network admin panel.

We tried deactivating Multisite Clone Duplicator and reactivating it hoping that it was some caching mismatch. This had no effect.

I’m afraid I don’t know what caused this to happen, as I was unable to reproduce it. Another admin was also making changes at the time and we believe that the blank screen/page was likely caused by something in this plugin getting triggered due to errors caused by other out-of-date plugins that were updated.

On further investigation, we found an option in wp_options that we believed to be associated with Multisite Clone Duplicator:

option_name: mucd_duplicable
option_value: no

We tried setting this option to “yes” and it seems to have fixed the problem. The admin page for Multisite Clone Duplicator now shows up and performs as expected.

If another person is having this issue here are steps you can take reproduce our solution. Beware, follow these steps at your own risk – I’m not a developer of the plugin and don’t know what this option is for! This worked for us in our specific case, do not use the following code unless you don’t mind breaking things on your website.

• You can check your setting in mysql using the following command:
  select option_id, option_name, option_value from wp_options where option_name='mucd_duplicable';
• You can update it to ‘yes’ with the following command:
  update wp_options set option_value='yes' where option_name='mucd_duplicable';

I’d like to ask the developers why a blank screen would happen.
Also, is the solution we used okay to use on a live site?
Is this the only way to solve a blank admin screen with Multisite Clone Duplicator?

Thanks for making an awesome plugin!

Darren
