Dear Support
Thanks for the fix. It works ;-)

BTW, Just to make it clear. I am not using this or any other template multiple times. I am Webmaster of several Joomla sites in Switzerland and I am recommending your templates to my customers. All used templates are fully licensed with you.
I just mentioned https://www.propellerclub-bsl.ch/ because I updated it two and faced the same problem, and was forced to restore the site again. Mentioned template is fully licensed (please see Account = PropellerClub / valid until 23.08.2018)

Kind regards
Arie
