XF 1 XenForo 1.5.16a - Full Nulled MOVED

Unfortunately, we have identified a regression in 1.5.16 related to recurring user upgrade expiry and refund/reversal processing. This issue can cause database errors to be logged and delayed downgrades. As such, we have patched this issue and updated the download to 1.5.16a to incorporate a fix for this issue. If your site does not use recurring user upgrades, this issue will not affect you.

If you downloaded 1.5.16a from here you do not need to take any other steps. If you are running 1.5.16 and wish you fix this bug, you may either:

1. Download 1.5.16a from your customer area and re-upload the files as if you were upgrading.
2. Change the patched file manually with the version from this bug report. Note that this approach will show these files as not containing the expected files in the file health check.

Please note that the version will still display 1.5.16 in your admin control panel.
