I was using WPUI on a wordpress 3.4.2 website with the custom styles working perfectly, they uploaded and away I went and it was fine.
I then upgraded to wordpress 3.5 and made a fresh install on a new server, now it doesn't work. Wont allow me to upload a custom theme.
I've deactivated it and activated it, tried everything i can think of... nothings working.
Is this a known issue, is there any fixes?
Thanks guys in advance!
