The following error may be received if you attempt to upload a theme or file larger than the default of 2MB...
"This file cannot be imported. It may be caused by file_uploads being disabled in your php.ini. It may also be caused by post_max_size or/and upload_max_filesize being smaller than file selected. Please increase it or transfer more substantial data at the time."
You may increase your upload limit from within your control panel with Ultra via the "MultiPHP INI Editor" icon.
Increasing both the upload_max_filesize and the post_max_size tends to fix these upload issues.
If you've tried all of the above steps and the error is still occurring, you may need to contact our support for assistance. We will be able to help you identify and resolve the issue.
