Hi, thank you for purchasing our theme.
It may be caused by the max-upload size of server config. Please try to use FTP to upload theme folder:
– Login to your FTP server and navigate to your WordPress themes directory.
– Normally this would be “wp-content/themes”.
– Extract folder “sea-theme” from the zipped theme.
– Upload the folder “sea-theme” to your themes directory by FTP.
– After the files finish uploading, login to your WordPress admin.
– In the “Appearance” menu click “Themes”.
– Click “Activate” for the theme “SEA theme”.
=============
If it doesn’t work, please send your question and wp-admin(URL / username/password, better with FTP account also) to uiueux@gmail.com, I’ll log in to check it.

Regards!
