I'm using old-style JIRA. For some reason, when I click the Search for Issues drop down at the top of the page, the search screen is missing the 'Search' text box. In fact, the whole screen looks different. Something has happened that has modified the layout of the Search for Issues screen. This issue began late in the day 1/9/2018.
I've closed and re-opened the browser, (Firefox). Rebooted the machine. Even shut it down overnight. Switched to Microsoft Edge. Still have the same issue.
Can someone help?
