Install Pro and enter your license key

What the license does

Your license key brings updates to WPMelon Product Customization Fields Pro. New versions show on Plugins like any other plugin, and you update with one click.

The license only brings updates. Every Pro feature keeps working without a key, after the license expires, and when our update server can’t be reached. Nothing is locked or removed, and your store never contacts our server for your customers.

Install Pro

Get the zip and your key

1. When you buy Pro, you sign in or create an account on the WPMelon helpdesk. Your license is linked to that account.
2. After payment, your key arrives by email, with the subject “Your License Key for WPMelon Product Customization Fields PRO”. The license also appears in License Management within a few seconds.
3. In License Management, open the license and click Download under Available Downloads. Keep the file zipped.

Install the zip

Go to Plugins → Add Plugin → Upload Plugin, choose the zip and click Install Now.

If you don’t have the free plugin, click Activate Plugin and go on to Enter your key.

Switch from the free plugin

The zip installs next to the free plugin, and only one of them can be active.

1. On the Plugins screen, deactivate the free plugin.
2. Activate Pro. Your option groups, settings and orders stay.
3. You can then delete the free plugin: Pro keeps using the same data. If your store isn’t in English, keep it installed but inactive instead: deleting it also removes its translations, and Pro uses them.

If you activate Pro while the free plugin is active, WordPress shows a “Plugin activation blocked” page and nothing changes. Click Go to the Plugins screen and deactivate the free plugin first.

Enter your key

1. Go to Products → Product Options → Settings and click Manage license in the License & Updates card. You can also click License & Updates under the plugin’s name on the Plugins screen.
2. Paste the key from your email into License key. It’s also on the license’s page in License Management. Then click Save key.
3. The status should read Active. Last checked shows when the plugin last asked for updates.

Only administrators see the license. Shop managers can use every Pro feature but don’t see the key or the License & Updates page.

The key is tied to the site address shown under Site. If you move the store to a new address, click Check again after the move. If the status says the site limit is reached, go to License Management, open the license and click Deactivate next to the old address, then click Check again.

Status messages

Status	What it means	What to do
Active	Updates arrive on the Plugins screen.	Nothing.
No license key entered	No key on this site.	Enter your key.
License expired: renew to receive updates	You keep the version you have; new versions aren’t downloaded.	Contact support to renew, then click Check again. Lifetime licenses don’t expire.
Invalid license key	The key isn’t one we know, or isn’t for this plugin.	Copy the key again from your email or from License Management.
Site limit reached: contact support	The key is already used on as many sites as your plan allows.	In License Management, open the license and click Deactivate next to a site you no longer use, then click Check again. For more sites, contact support.
Site pending approval: contact support / Site not authorized: contact support	The site needs approval for this key.	In License Management, open the license and click Approve next to the site under Pending Domains, then click Check again. If it isn’t listed, contact support.
License banned: contact support	The key was blocked.	Contact support.
Unable to verify license	The plugin hasn’t asked our server yet.	Click Check again.
License validation error	Our server couldn’t be reached, or answered something unexpected. The message under the status gives details.	Try Check again later. Your features keep working.

When the license needs your attention (no key, expired, invalid, site limit), the Plugins screen shows a line under the plugin, with a Manage license link to this page.

Check again and remove

• Check again asks for updates and the license status right away. The plugin otherwise checks twice a day, during WordPress’s own update checks.
• Remove key removes the key from this site only. The site keeps its place on your license until you click Deactivate next to it in License Management.

Debug log (for support)

If updates don’t arrive, support may ask for a log:

1. Under Debug log, tick Log the update checks, for support and click Save.
2. Click Check again, then Download log and send the file to support.
3. Untick the box and click Clear log when you’re done.

The license key is masked in the log (only its first and last four characters show).

Deleting the plugin

Deleting Pro keeps your license key, so you can reinstall the zip by hand and keep receiving updates. With Remove all data when the plugin is deleted on (Settings tab), the key is removed too.
