Why Does My Popup Have No Background and/or Styling?

Upon activation, the Popup Maker plugin installs 6 popup themes. Popup Theme settings are located in the WordPress Admin at 'Popup Maker' -> 'Popup Themes'.

By default, each popup is set to display a popup using the 'Default Theme'.  Plugin users have the option of selecting any one of the 6 popup themes to style their popup. Each existing theme can be customized.  

Plugin users may also add and setup a custom popup theme.  Go to  'Popup Maker' -> 'Popup Themes', and select the button labeled 'Add Popup Theme' to set up a new theme.

The selection of a popup theme is set in the Popup Editor at:  

  • 'Popup Settings' box -> 
  • 'Display' option tab -> 
  • 'Appearance' option category -> 
  • 'Popup Theme' selector. 

If a popup has no background or styling, it may be due to one of several factors. These could include:

Issue Comment
No popup theme was assigned An unlikely scenario, because by default the plugin should assign the 'Default Theme' at 'Popup Settings' -> 'Display' -> Appearance'.
The plugin file that builds the popup themes was either modified or deleted Inspect the plugin file directory and search for: '/popup-maker/includes/admin/themes/metabox.php'. If the file is missing, reinstall the plugin. 
There is a JavaScript conflict on the site that is interfering with the loading of the Popup Theme. Load your site URL, and then open the browser's 'Developer Tools' -> 'Console' tab and check if one or more JavaScript errors are present.  If so, this may indicate an issue that requires further investigation to resolve the matter.
