Hi Olga,
The problem actually occurred because we have copied one of the sites but then bought another license for the other site.
I don’t have the FTP access but I can provide you the login details. Would that be enough for you?
I have already tried deleting and re-installing the themes, deactivating and activating the themes with the purchase codes but nothing helped.
I also noticed the same problem mentioned on the forum. Would it be nice if you could share the fix publicly, instead of doing it yourself?
Thanks
