Hello,
You need to increase uploading limits on your server. We suggest you contact your hosting provider for help in this situation or upload the theme via your hosting control panel. Make sure to mention the file size you’re trying to upload so they can increase the upload and execution limits accordingly.
It’s usually due to one of the following reasons:
File Size Limit – Your hosting provider may have an upload size restriction.
Incorrect ZIP File – Make sure you’re uploading the theme ZIP only, not the full package.
Server Timeout – Some servers time out during large uploads.
If you have any questions, feel free to contact us. If you need help, share the WP admin login details and Cpanel login details of your site so I can check and upload the theme to your site.
Best Regards,
