@arminunruh ok I downloaded a different version of the zip file without selecting carousel, lightbox or fullscreenslider and this seems to work. Hopefully that won't mean I miss out on features down the line. I found this whole process pretty complicated to be honest and I am reasonably experienced in building websites using various different platforms. I think you should consider adding a clear description to your site regarding the difference between the wordpress.com and wordpress.org set-ups so that people know exactly what they are signing up for. Thanks.

@arminunruh Thank you, after a crisis session with a tech friend I have managed to successfully install Wordpress and the button has appeared. But now the problem is when I try to install the Lay theme from the zip file - it says this: The package could not be installed. The theme is missing the style.css stylesheet. Theme install failed. What do you recommend I do?

Please help - there is no 'add theme' button showing up on my Wordpress admin dashboard! I went to Appearance > Themes and there's no option to add theme anywhere on the page?? I've followed the Lay installation instructions to the letter, tried some bug fixes, checked out Wordpress.com / Wordpress.org, tried doing it in several different browsers and tried investigating via the cpanel on my web hosting. I've trawled this forum and others and there's no definitive answer anywhere about how to fix this. I'm using a new computer so all my apps are up to date. Please can someone help me so I haven't just wasted $200 on a theme and hosting that won't work...? Any advice appreciated!!
