ThemeExtras Plugin - Allows themes to define custom fields and settings

[johnstray2001]

@ufopera: The method I’ve used for string concatenation in the variable declaration is compatible only with PHP 5.6 or newer. As I am not supporting versions of PHP older than 5.6 (because they are way too old for production use), I probably won’t be adding a fix in a future version of the plugin.

In your case, you have 2 options, you could either update to a newer version of PHP, or use the workaround that you’ve provided in your post.

Also, as stated in the first post of this thread, you can find information about the theme.xml file by checking out the documentation for the plugin (link at top of first post). A full example is also provided in the GitHub repository within the themes/Innovation folder.
