Are You Sure You Want to Do This?
While installing your theme through WordPress admin, you may encounter this error message. This is most likely due to your hosting php.ini configs.
The theme file is around 3mb and some servers set the default value for max_upload_limit to 2mb.
There are two ways to solve this issue:
Upload theme via FTP: You can install the theme via FTP upload method.
Change php.ini file: To solve this issue, you should either increase your maximum upload size to 10mb on your hosting or ask the hosting provider to do it for you. This is a very common request and they should be able to help you out. Once the limit is increased, you can re-try the install.
