 * Do you have any other plugins installed? Perhaps any plugin that modifes what
   a user can and can not do?

 * Still not sure why this happens. Installed the User Roll Editor-plugin, but still
   no error here. Anyway, I’ve made some small changes to Simple History to prevent
   that error from happening. You can wait for the next version of the plugin to
   be released, or you can try to download the latest version from GitHub and see
   if that works: [https://github.com/bonny/WordPress-Simple-History](https://github.com/bonny/WordPress-Simple-History)

 * That fixed it but I wanted to look into why it may be causing it on my end based
   on what you said. Turns out it was my fault. I recently renamed be database prefixes
   for security and forgot to update the options table on the subsite table. Once
   I ran UPDATE `NEWPREFIX_2_options` SET `option_name` = REPLACE( `option_name`,‘
   OLDPREFIX_2_’, ‘NEWPREFIX_2_’ ) the issue went away.
