About the problem of plug-in “the creator”

hello

I am Japanese.
This sentence is written using Google translation.
I am sorry if there was a confusing part.

I purchased “Shard - Multipurpose Business Parallax WP Theme”. ,

After activating the theme, we also enabled some plugins
There is one problem with “the-creator-vpb”.
That means that if you choose Element → post it is unresponsive.

Elements that are moving may also disappear with drag and drop, or even if you press done after editing an Element, it may be unresponsive. (I will save it, but …)
There is nothing wrong with the creator’s demo page.

I asked twice the question about “The Ab-themes” which is the author of the theme about this problem but there was no reply after more than one month.
Since it can not be helped, I contacted the “Envato Market Help Team” about this matter.
The people of the Help Team were very kind and contacted the author, but even if one week passed, there was no contact from the author. “Ab-themes” seems to have abandoned support.

The Help Team gave me advice on how to get hints at the forum.
(I do not know if it is OK in this category …)

“the-creator” plugin download link. (the - creator - vpb.zip)

Please let me know if you have any information on resolving the problem.

Wordpress is version 4.9.6 and is a PHP 7 environment.

Please give us good support.
