If you bought SNIP on CodeCanyon, you subscribed to a 6-month (or optionally to a 12 month) support plan that expires automatically after that time. After that you need to renew your support in order to get one-to-one support via E-Mail. Here is how you can do that.
This error occurs due to the fact that CodeCanyon only sells licenses that are available for one domain only. If you’re trying to install the plugin on multiple domains you will get the following error on the second domain:
“It seems that this purchase code is tied to another host. Please buy a new license in order to use this plugin on another sites.”
It seems that this purchase code is tied to another host and/or IP address. A purchase code can only be linked to one domain at a time.
In general, yes but there are limitations. Some of the plugins out there (like AdvancedCustomFields) save their data into the wp_postmeta database table. From there you can use the saved data to include it into your snippets.
