I am trying to reupload the theme at present since the folder structure is not right. Things won’t be reliable if the theme is located inside a subfolder and even WordPress admin get cranky when this happens – it is not allowing me the delete the theme saying – Deletion failed: The requested theme does not exist – though the theme does exist and does activate.
The folder structure should be –
http://annakozh.com/wp-content/themes/cosmic/
and not
http://annakozh.com/wp-content/themes/themeforest-8955992-cosmic-app-landing-multipurpose-wordpress-theme/cosmic/
I have uploaded the theme again that goes into themes/cosmic folder and activated it. The site is working great and is really smooth on my mobile as well as desktop and results here – https://tools.pingdom.com/#!/bttQ82/http://annakozh.com/ confirm the same.
Pls delete the subfolder themes/themeforest-8955992-cosmic-app-landing-multipurpose-wordpress-theme/cosmic/ through FTP since WordPress does not let me do it through the admin interface.
Pls let me know if you need help uploading the sample data (recommended) and we can help import the same for you so that you get a head start on your site. Good luck.
