A common issue that can occur with users new to installing WordPress themes is a "Broken theme and/or stylesheets missing” error message being displayed when trying to upload or activate the theme. This error message does not mean that the theme you have purchased is broken, it simply means it has been uploaded incorrectly. Luckily, there is a very easy fix.

When installing, at the ‘Import Content’ step, please select ‘Extra Data’ to have all the data. The ‘Essential’ option is only for customers installing on an existing site who do not want to import new data or new pages and only want to use the homepage. Please read MORE

Many issues that you may run into such as white screen, demo content fails when importing, empty page content, and other similar issues are all related to low PHP configuration limits. The solution is to increase the PHP limits. You can do this on your own, or contact your web host and ask them to increase those limits to a minimum as follows:

max_execution_time 180
memory_limit 128M
post_max_size 32M
upload_max_filesize 32M
