My ReCaptcha wasn't working. I haven't done the full plug-in conflict test because I'm sure that the only change was the creation of a popup on this page: http://www.sharinghousing.com/worksheets designed to force users to register before downloading. I hired a local person to create it. I've deleted recaptcha from the forms that was using it. I'm writing to find out what I can do to replace recaptcha? I don't know enough to tweak the programmer's code. And I dont' really want to hire him to fix it.
At least these are my thoughts about why it wasn't working. If you have others? I've been through the forums...
Thanks!
