# Javascript Error

 * I experienced an odd error whilst using the calendarize.it plugin. There are 
   3 Admin accounts, mine worked fine but the others could not edit an event post.
   The plugin author investigated for me as I hadn’t got a clue and identified:
   `
   Uncaught ReferenceError: wmpUi is not defined.` `Deprecated TinyMCE API call:
   <target>.onMouseUp.ad(..)` when the other admins were trying to edit an event.
   With your plugin deactivated it worked fine. I want to keep using your plugin
   but obviously can’t at present, any ideas?

 * Hello [@nigel7119](https://wordpress.org/support/users/nigel7119/), I hope all
   is well!
 * Can you replicate the same error when only the Custom Sidebars plugin is activated?
 * Deactivate all other plugins and test if the other admin accounts can edit a 
   post. If everything is well, activate one plugin at a time to find the one that
   causes this.
 * Please repeat the same to check for a conflict between the Custom Sidebars and
   Calendarize.it plugin. Switch to a default WordPress theme, leave only the two
   plugins activated and try to edit an event just to make sure both plugins are
   in incompatible with each other.
 * Follow the flowchart from our Getting Support manual:
    [https://premium.wpmudev.org/manuals/using-wpmu-dev/getting-support/](https://premium.wpmudev.org/manuals/using-wpmu-dev/getting-support/)
 * Let me know how it went.
 * Cheers,
    Nastia
