A small number of authors, especially those in China (related to the great Chinese firewall which blocks javascript), experience technical issues while submitting to our journals.
1. Check that your browser is not blocking Javascript.
This will depend on which browser you are using. Instructions can be found here (https://www.enable-javascript.com/)
We always recommend using the latest version of Chrome or Firefox to avoid technical issues.
2. If you are sure that Javascript is not the issue, you may submit a ticket to tech-support@jmir.org, attach your manuscript file and a screenshot showing the submission page where you are stuck or where you see an error message. In exceptional cases we can submit on your behalf. Please make sure that your manuscript file follows the template listed here.
