All published websites require an active license on Site.pro. Each published website periodically sends a request to Site.pro (or the On-Premises website builder) to validate its license. When license validation fails, the website is blocked and the message "Website is temporary unavailable" appears. Below are the reasons why this may happen. Obvious reasons: Your license has expired — renew your license by making a payment;Your license exceeds the number of live websites — renew your license by choosing a bigger package and making a payment. Other reasons: The website was manually blocked via the statistics page or the Site.pro API. Check the "Domains" tab on the statistics page — a green "Blocked" button on the right means the website is blocked, or check via the Site.pro API. Press the green "Blocked" button, or use the Site.pro API, to unblock the website;The published website is hosted on an IP address that isn't added to your Site.pro account. License lookup during validation is done by IP address, so if the IP is missing, the license isn't found and the website gets blocked. Site.pro adds missing IPs automatically after some time, and the website starts working on its next validation. To fix this instantly, add the website's IP address (the domain's DNS IP) to your brand in your Site.pro account manually, then trigger an instant license re-validation;The website was migrated from one website builder to another — even between different Site.pro accounts, for example when a customer migrates from one hosting to another. If it was migrated "from On-Premises to Cloud" or "from On-Premises to On-Premises", the website still holds info about the previous builder and keeps calling it for validation, causing an error. Re-publish the website in the website builder so it gets fresh builder info, then trigger an instant license re-validation;The website was last published a long time ago, when the token mechanism may have contained bugs that could cause a false-positive block. Re-publish the website in the website builder so it gets fresh builder info, then trigger an instant license re-validation. These are the most common causes of a blocked website and how to resolve them. Instant website license re-validation:Normally, a published website sends a license validation request once a day (or less often if the website is inactive). To force a license re-validation: Remove the file "data.json" from the published website, located in the "sitepro" folder;Open the website in a new browser session, for example in an incognito tab. The website's license is now re-validated.
