Updating Board3 Portal 2.0.x & phpBB 3.0.x to Board3 Portal 2.1.x & phpBB 3.1.x

As Board3 Portal 2.1.x switched from the MOD system in phpBB 3.0 to the new extension system, it introduced major changes that break backwards compatibility. Due to this, a direct update from Board3 Portal 2.0.x to 2.1.x is not available.

Make sure that you uninstall Board3 Portal before attempting an update of phpBB to version 3.1.x. Otherwise, you might have corrupted ACP modules in your system.

Otherwise, you might see this error message after clicking on the extensions tab in the ACP.

General Error
Cannot find module ./../includes/acp/\board3\portal\acp\portal_module.php

Open the ACP and click on the system tab. Then click on Administration Control Panel below Module Management in the left side bar. Afterwards, click on Extensions. You should see at least one category called Portal or maybe ACP_PORTAL_INFO. Remove any of its sub modules and afterwards remove the category itself.

Make sure you do not have the extension installed while you do this. Once you have removed these old modules, you should be able to fully install the portal and also access the configuration once you click the Extensions tab in the ACP.
