Nothing has changed with the database. If you see a blank page with just the plant name in an entry, it just means no one has added any of the details. All info is added by members or admin. and we are all volunteers with busy lives. Any member is free to help out by adding details.
If you are seeing ads, you only need to add 5 more contributions to the database (for a total of 100) and you can then go to your profile page and in the settings, you will see an option to turn off ads.
