We at Morressier are just the technical partner for our conferences. As such, it is not up to us to extend deadlines for authors.
However, you can always contact the Conference Organizers directly to see if they are willing to accept a late submission.
You can usually find their contact details through the event website, but if you cannot find them you can always contact us at [email protected] and we can find it for you.
This also applies to wanting to upload a revised version of your paper once the submission deadline has passed. The Conference Organizers can change the status of your submission to 'Changes Requested' so that you may make a resubmission.
NOTE: If the submission deadline has not yet passed and your paper has not been reviewed, you can still upload an updated paper as a new submission through the original Call for Papers link. You should then go into your My Submissions tab and withdraw your first submission, to avoid any future confusion.
In case your paper has already been reviewed, please contact the Conference Organizers directly.
If you need further support, please get in touch with us using the chat icon in the bottom right corner so email us at [email protected]
