All that did for me was give me a better looking “Sorry, something unexpected occurred during installation” notification. Additionally, there is no way to escape the notification (requires page reload). Can you please just provide us with a ZIP of the content files for the different demos with FTP installation instructions? Or better yet, put them in the theme folder for everyone else who might pick up the theme in the future? My client pre-paid me for this project so I am very frustrated that I cannot give him what he wants as fast as I usually can. Thank you.
So I have done everything, including changing the PHP max_execution_time and/or the memory_limit settings as suggested by Documentation. Still does not work. Please provide us with manual install files for Demo Content.
