If you bought SNIP on CodeCanyon you subscribed to a 6-month (or optionally to a 12 month) support plan that expires automatically after at 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.
Not really automatically but kind of. You still have to initiate the update in your dashboard but you can get the update right in your WordPress dashboard without manually download/upload the plugin files.
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.”
A) I’m getting the error while updating.
If you get the error while updating, please try the following:
Login-in to your WordPress Dashboard
Go to snip -> Settings.
Click the “Clear Cache” button.
Go to snip -> Activation.
Click the big blue “Let’s get started” button again.
If you get an error here, please read B).
Then go back to Dashboard -> Updates.
Click the gray “Check again” button.
If you still get an error, please read B).
B) I’m not using it on other domains
If you think you’re not using the domain on another host, please contact support.
C) I want to switch to another domain
Of course that’s possible, too. Follow these steps:
C1) If you still have access to the old site
Log-in to the site where SNIP was originally activated (old site)
Go to “snip / Structured Data” menu and click the “Support” sub-menu item.
On the right hand side you’ll find a metabox with a button labeled “Deactivate license on this site”. Press this button.
The plugin will then de-activate and de-register itself.
After this, you can use the purchase code on the new site.
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.
