Where does xenForo stores its "I will be updated" information?


Well-known member
When I upload new files, xenForo notices that and stops running the forum until the upgrade process is finished.

However when I overwrite all existing files with the former files, xenForo still wants to be upgraded.

Where does xenForo stores its information about the update process? I am really curious.

xenForo creates the file internal_data/install-lock.php, when you remove it xenForo doesn't know anymore about any updates.

Yeah, but removing that would also allow your install to be wiped and overwritten by a clean install. You don't want to do that.

XenForo detects there is an upgrade pending when the version ID in Admin CP > Options > Debug Options no longer matches the version ID found in XenForo_Application::$versionId.

Therefore, replacing the files from the currently installed version should be fine.

Make sure Application.php copied back over correctly.
