The documentation needs to be updated as in nopCommerce 4.30 there is no longer Nivo slider and also we added support for HTML out of the box so no need to use caption anymore.
Hi David,
You won't have any problems with our themes (I can't comment for other themes from other vendors).
Even if you have any issues you can always submit a ticket and we will help you out.
With the theme purchase, you get 1 year of free support and updates.
We are working on adding 4.40 support in our themes and we plan to release them by the end of the week.
