Please check the Javascript console for errors. You can also check XenForo's error log to rule out a hidden database error.

XenForo.activate(%o) [object XrayWrapper [object HTMLDocument]] xenforo.js:221
"XenForo.init() %dms. jQuery 162/1.11.0" "1.2.8-dev" xenforo.js:209

No error logs in XF.

It's possible scripts aren't loading. Are there any 404s?

Note that this behavior was reported in Gamma 5, but we discovered it had to do with a race condition in the Javascript event subscriber: https://www.vaultwiki.org/issues/3730/
Please double-check that your /vault/resources/js/xf/base.js includes the word "kindle", since that would be the fixed file.

I have sent you the error log.

According to that log, it looks like you may need to revert some customized templates. Are there icons missing in a lot of places? If only in some, please let me know which. Check admin.php?templates/outdated to make sure it's not related to an outdated template.

It looks like there is a race condition in our download system. If the download asks for a compressed version of a file, it does not wait for the compressor to start up before moving on and trying the next file. Sometimes this results in 2 or 3 Javascript files being downloaded with empty contents. As this is a race condition, it's very difficult to reproduce, but I've made some changes that should at least let it use the uncompressed file if the compressor isn't ready yet. I've replaced the affected files on your site. As this issue is related to our server configuration and not really with the VaultWiki source code, I've marked this appropriately.
