I always can create tasks from any page of jira - filters, main page with tasks, backlog. I just use button Create, fill fields and use button "Create" in the bottom of window Create Issue. After that Jira shows
Today Jira stoped showing me a pop-up after I created a few tasks. Pop-up I mean information "New task has been created [task number]" on the top right corner of page next to search field.
Only space when I can create task and wverything works corretly, I mean Jira shows pop-up is page with Filters.
