I just tried to upload a photo to the plant database. I got the page with the green button to click to upload a photo, but clicking on it did nothing (as though it did not see/register the click). I opened another tab, linked to the site, and tried again - nothing.
This was in the Chrome browser.
I opened a window in Microsoft Explorer and repeated the attempt. I was asked for my name and login, and once supplied, the site sent me to the page with the upload photo button. This time, clicking on the button allowed me to proceed and upload the photo.
