Please advise how to install the theme. Which of the zipped items do I upload to get the theme installed? I get an error message that "The entity is too large".
You should upload the MaxCoach.zip file. For more information please visit this URL.
Please read this article below about the Theme Requirement
and make sure the PHP configuration limit as below
max_execution_time=600memory_limit = 256 MBpost_max_size = 100 MBupload_max_filesize = 100 MBMax input Vars = 5000
Therefore if you failed to upload the theme then share us your WordPress credentials after changing the user/pass to look it more closely to solve the issue.
