Hi, there is an issue with the Audentio Xenith Style and the TMS entry to set the wmtech copyright. Take a look at www.xendach.de The issue can be fixed with a change in the footer TMS for the XFLicenseValidator AddOn. Change the search type from regular expression to PHP Callback..
This is not a bug, but rather an oversight. We have already corrected the zip file (without changing the version). So everyone downloading now will get the correct XML file. Thanks for reporting!
