Security
Valid SSL certificate
Your store should run on HTTPS so the licensing handshake can complete properly.
License activation
Activate the extension on the correct domain without losing time
The license activates automatically after the order is completed, the extension is installed correctly, and the server can reach the licensing system.
- Typical activation 1-2 business hours
- License scope One declared domain
- Server check HTTPS and access to the license host
Activation flow
How activation reaches the store
There is no separate activation form. The license unlocks automatically once the order is complete and the extension runs on the right environment.
- 01
The order closes
The order must be fully paid and marked as completed before the license can be issued.
- 02
The license is issued automatically
The licensing server recognizes the purchase and ties the license to the domain that was declared during checkout.
- 03
The extension unlocks on the declared domain
Once the server can validate the license successfully, the extension runs without restrictions on that domain.
No manual request is needed
When the order, domain, and connectivity are correct, the extension activates without extra action from your side.
Required checks
What must be in place before you review the case
Most activation issues are not extension bugs. They come from the environment, the domain, or the server connection to the licensing system.
Network
Access to license.opencartgreece.gr
Firewall rules, hosting policies, or outbound restrictions must not block outgoing HTTPS requests.
Installation
Correct install on the licensed domain
The extension must be installed on the same domain that the license was purchased for, not on a different alias or subdomain.
Common blockers
Four reasons a license warning usually appears
Start with these scenarios before you ask for a deeper support review.
The purchase is not fully completed yet
If the order is unpaid or not marked as completed, the license is not issued.
The extension was installed on a different domain
Even a small change in the domain or subdomain is enough to break the license match.
The server cannot reach the licensing system
If the server cannot contact license.opencartgreece.gr, the extension cannot confirm the license.
The environment changed abruptly
Major changes in OpenCart, PHP, or hosting can introduce incompatibilities or new outbound restrictions.
Quick answers
What to do when activation does not complete
The most common questions around the license message and the next action to take.
I see a license warning right after installation. What should I check first?
Confirm that the order is completed, that 1-2 business hours have passed since the purchase, and that the extension is installed on the same domain declared during checkout.
The extension used to work and suddenly stopped. What may have changed?
Usually the domain, the hosting environment, outbound server rules, or the OpenCart and PHP versions changed in a way that affects the license check.
Can I move the license to another domain if the store changes?
Yes, but transfer rules apply. If you are still inside the 10-day window, review the transfer guide first.
Still locked?
The license did not activate after the base checks?
Send the order number, domain, extension, and screenshot to the team for a targeted review. If the issue is actually a new domain, review renewal or transfer status as well.
