 * This is a site with no other plugins on it, so it’s definitely your plugin. Tried
   to troubleshoot myself but couldn’t figure it out.
 * FYI, the plugin worked fine prior to this update.
 * Thanks!

 * Now for the why: The internet is a wonderful place full of very nice people and
   a few very bad ones. I’m sure everyone here is very nice however, by giving some
   ones keys to your house you are trusting they wont steal anything. Likewise the
   person who takes the keys is now responsible for the house FOREVER.

 * Hi [@ideasandpixels](https://wordpress.org/support/users/ideasandpixels/),
 * I have created multisite and I don’t have problem with it. How can I simulate
   your problem?
 * Try creating a clean WordPress installation, create a multisite on it, and tell
   me if my plugin is getting an error. If so please share me code and dump database
   of site. There will be no confidential information there, because it’s a clean
   installation.

 * [@ideasandpixels](https://wordpress.org/support/users/ideasandpixels/) I fix 
   for your problem in the latest update. Please download and check it. Let me know
   if everything works.
 * Can you add a review for my plugin? I will be very grateful!
