Some webservers have a limitation for the maximum allowed size of files being uploaded to them and that value may be exceeded by the theme file. If that is the case you can receive an error that states: The uploaded file exceeds the upload_max_filesize directive in php.ini. or Are you sure you want to do this? Please try again. If you get any of these errors please increase the values of upload_max_filesize and post_max_size directives in your php.ini file to 20M or follow the Installation via FTP section described above.
All the plugins which are not free come under our Extended License, so you don’t need to pay for their license to use them. Some of them might have messages requiring activation, but they are already activated on our side. No purchase code needed. When using them under our license you will need to wait for the plugin updates in our regular theme updates. If you want to be able to auto update them from wp-admin, you will need to buy your own personal license for that.
