Frequently Asked Questions

Can I continue to use plugin after the license expires?

Yes, if you decide not to renew your license, you can continue to use last plugin version you have downloaded for as long as you like.

Will this plugin work on WordPress.com hosted websites?

Yes and No. WordPress.com is a closed system and you are not allowed to install plugins there on your own. To use this plugin you need to have your own hosting setup for WordPress. But, WordPress.com Business accounts can install plugins, and you will be able to install Dev4Press plugins too, but there is no guarantee that each plugin will work there.
