Widgets Control Pro conflict

Posted in


We have several sites with both The Event Calendar Pro and the Widgets Control Pro plugins enabled and in use. Unfortunately when we try to customize a page that has an Event Calendar widget visible we get 2 javascript errors caused by a javascript variable on the page being equal to nothing. the variable is _wpWidgetCustomizerPreviewSettings
If we disable either plugin or hide the offending widget from that page we don’t get the error and the variable has a value.

Any assistance you could provide on this topic is appreciated. I would be happy to provide any additional information you may need on this topic. Unfortunately I can not give you admin access to any of our sites.

Thank you,

    Thank you for your attention in this matter. Fortunately we have updated other plugins and the issue seems to no longer be an issue. I like problems that fix themselves 🙂

    Feel free to close this ticket/issue.

      Hi Louis,

      That’s great to hear. Automagically resolved issues are the easiest 😉

    Sure I’d be happy to help – could you please let us know about the current versions you are using:

    – WordPress
    – The Events Calendar or Pro
    – Widget Control or Widgets Control Pro

    A screenshot or full console error report when this is happening would be helpful too please. You mention that this happens when you try to customize a page, are you using any page builder or blocks? I would need to know under which exact circumstances this happens so I can try it under the same conditions. If you can provide access to a staging site, that would also be sufficient.
