Unable to upload model to Sefaira web application

I am unable to upload or even use the ‘template’ on Sefaira web application to create a new model. The ‘Space type’ tab does not show any drop down list and hence no inputs possible to proceed into the main model simulation/ web application’ page. ‘Sorry something went wrong’ pops up.

This error come up irrespective of type pf model or web browser used. Appreciate your help asap. Thanks!
