Hi,
I don’t think this is the reason. I contacted the hosting provider, but as you can see in Server Requirements, all requirements are met.
I reinstalled a fresh copy of wordpress and theme and now when I try to import the default demo, I get the message that the pages etc can’t be created.
I don’t know how to send you screenshots to see what I’m talking about, but if you want, you can try to install the default demo and see what happens.
Thanks!
