Hi dear friend,
Hope you are fine,
I have investigated your website, demo has imported completely and I did not face any issue with it.
Would you please explain what is the exact issue?
If the problem you mentioned with the dummy date is related to the images,
I have to say that our dummy data does not include photos and when you import our demos, they see gray boxes instead of the images.
The photos that are used in our online demos are being purchased by us for our demos.
Please read the following article:
