After much testing there seems to be an issue that if you enable a few plugins (>2) that add functionality to the "start a discussion" screen, the layout breaks badly on mobile browsers. Effected are such vital plugins such as file upload, private discussions, BBCode editor etc.
This seems to be a Flarum core issue, so I am wondering if this was improved in beta8?
Would be nice if this was added to the beta8 roadmap if not already on it or fixed. Thanks!
