We have update CubeWP Framework plugin and added an option to switch off our single page template, SO now if you want to create your own single page template you can switch off our option from cubeWP settings > Post settings.
Also if you want to create single page using any builder or editor then definitely you need to fetch single post data dynamically, For that purpose we have created a shortcode,
[cubewp_post_field field=YOUR FIELD NAME]
You can use this shortcode to get any field’s data. This shortcode gives data after rendering, Like if you get any image field data, It will return data with img tag,
Same way if you get post field data, it will return post title with anchor tag,
and all other text fields will provide same text data,
