Licensing System & Admin Users

We often get asked how licensing works with respect to users. So, here is the explanation of PHPKB's licensing system. The licensing system of PHPKB knowledge base software is based on the number of Admin users. The license restriction is on the number of admin users (staff logins) that can be created to login and update your knowledge base. Admin users include Writers (Authors), Editors and Superusers. There is no limit on the number of end-users that can access the public area of your knowledge base. So, you can have unlimited end users (readers) who can browse your knowledgebase and login to Public Area.

What is an admin user account?

An admin user account is a user that would be able to login to the admin area, create/manage articles, and be an author or admin. You can have unlimited "public" users (readers) with all license options.

Can I upgrade admin users later?

Yes, you can always choose to add more admin users in the future to your existing license. You need not to pay full amount for upgrade. All you need to pay is the difference between the cost of upgrade license and your already purchased license. For example, If you have purchased 5 admin user license of PHPKB knowledge base software and you'd like to upgrade your license for 15 admin users, then you need to pay the upgrade cost for 10 admin users only.

How many users can view our knowledge base?

There is no limit on the number of users that can view the knowledge base. If you do not plan to restrict access to your knowledge base, people would not need any special accounts to view your knowledge base. This means you can have unlimited number of users that can access the public area of your knowledge base. They can do this in the same way as they view your website.

Support & Upgrades

All license purchases include free technical support (Basic Plan) for 12 months from the date of purchase. If you wish to opt for Premium Plan (that includes free upgrades) in the first year itself, you can do so from your customer area. Our support hours are 9:30 AM - 5:30 PM CST. Please note that you are under no obligation to pay for future support and upgrades, you own your license, it is only if you want support and upgrades at the end of your free year.

Difference between Basic & Premium Support Plan

Our premium support includes web based (email and tickets), phone call and live chat technical support along with access to upgrades. Premium support tickets are sent directly to the technical support team allowing users to communicate directly with PHPKB staff to receive first-hand assistance with any problems or questions they may have regarding their PHPKB Software.
