There are literally thousands of different operating system, internet browser, and hardware combinations that can be used to access the DB site, not including mobile devices. We have a staff of one and an annual budget of about $100 to make the site function. We spend hundreds of hours a year of our spare time managing user accounts, installing software updates (to keep your private information as secure as possible), testing the site, keeping the content up to date, and assisting people with problems. Unfortunately, under these constraints, it is not possible to make the site function 100% of the time for 100% of the users.
