I’m 100% sure that the example websites are running the latest version of the plugin. For our testing practices, you can view this article
Here are some options to try, there is no need to move to a new website, server etc.
1) Activate the stock wordpress theme. Nowadays, wordpress comes with 4 themes, pick one. Does the issue persist?
2) Try one of our $1 one dollar wordpress themes. Does the problem persist?
3) Purchase 1hr of product support. If it turns out that the plugin does have an issue, you will be refunded 100% of the cost for the hour. You can choose to get that refund via paypal or credits you can use here
Let me know before purchasing so that i can alert a project manager
