Please beware that if you are using any version of VaultWiki acquired before June 1, 2023, if you have or will update to the newest XenForo version 2.2.13, you may experience fatal showstopper issues on your site while using VaultWiki, due to incompatible code changes introduced in that XenForo release, specifically while XenForo's debug mode is active.
We have now patched the issue from our end. We strongly recommend that any users running VaultWiki who also plan on upgrading to XenForo 2.2.13 or higher should upgrade VaultWiki to version 4.1.7 using the updated package available starting June 1. If you are already running VaultWiki 4.1.7 from an earlier date, you can download the package again and simply replace the files in your installation with the patched files.
Have a great day and thank you for your continued support!
