The Research Database is now open again after the upgrade. See information about the first log in after the upgrade.
When you first log in after the upgrade, you need to hold down CTRL and press the F5 key. If the page still does not look as it usually does, you may also need to clear your browser cache via the menu at the top right and then history -> clear browsing data -> clear data.
Note! This only needs to be done the first time you log in after the upgrade.
See the document below, how to clear the cache.
(The image and information on how to clear the cache are for the browser Chrome. It could be slightly different on another browser.)
