We'd first recommend you resetting your password if that's appropriate. If that doesn't work, we would try the following:
-Refresh your page
-Try a different browser (i.e Chrome instead of Safari)
-Search for the site in an incognito browser
-Perform a hard refresh
If you continue to have issues, please let us know what browser and device you're using at firstname.lastname@example.org with a screenshot of what you're seeing!
