 * Hi, we’re getting a fatal error from latest version of wp-activity-log when using
   our cloner plugin, please see below:
 * [24-Apr-2023 22:15:28 UTC] PHP Notice: Undefined index: blog in /home/9999999.

 * Not sure if this is related to the other reported sensor issue. We had to network
   disable the activity log to get our cloner plugin to work.
 * thanks.

 * Thank you for using our plugin.
 * I am sorry to read about your issue. Can you please let us know what plugin are
   you using to clone the website?
 * Also, when does this happen? When you try to clone a website or when you do something
   else?
 * The more information you can give us the better we can understand the context
   and the issue.
 * Looking forward to hearing from you.

 * Hi Robert,
 * Thanks for your response. We use NS-Cloner to clone sites. The cloner works fine
   with your plugin for other functions, just not the cloning of a new site. It 
   processes the first step – inserting a new blog record to wp-blogs – then dies.
   No tables are created or files transferred etc. Disabling the activity log plugin
   when we clone sites allows ns-cloner to complete with no errors.
 * Please let me know if you’d like more info etc.
 * Best,
 * -Jocelyn

 * Just to confirm, this is the plugin that you are using to clone the websites,
   right?

 * Hi Robert,
 * Yes, that’s correct, we use the pro version: [https://neversettle.it/wp-cloner](https://neversettle.it/wp-cloner)
 * (Looks like they just changed the product name to wp-cloner from ns-cloner).
 * thank you.
