Are you sure you want to do this? Message when installing child themes
This error usually occurs when your host has limited the size of files that can be uploaded to WordPress. To ensure smooth experience with most themes and plugins, your upload limit should be at least 10MB. Please contact your host or WordPress admin to request they increase it.
If the upload limit is not the issue, ensure you have full administrator rights and that your “uploads” folder located in wp-content is set to 755 or 777 to allow uploads.
