WordPress isn’t accepting my theme demo files. Help me fix this?

“The file is an invalid widget file” — An error mssg i get when trying to upload the demo content of a theme: customizer.dat and the widgets.wie file using the One Click-demo import plugin!

The demo-content.xml was accepted and uploaded successfully but these two files aforementioned aren’t uploading successfully.

WordPress always return an error message on the long-run. I’ve switched to another plugin for the demo import but it’s still not working irrespective of the fact that the plugin was made by the Theme source.

I downloaded the third party theme from catchthemes.com, and all things encompassing including all of its import files. The theme’s name is Devotepress…

Besides, I am not very familiar with how the WIE file looks like. The same applies to the customizer.dat

This is a link to the files on GitHub, just take a look at them abeg — Devotepress files on GitHub (by catchthemes)

This is a link to the theme Incase – Devotepress on Catch theme directory.

Please get back to me coz my website is currently blank and I definitely need to complete the set up in no distant time
