Every time I get on farmville and there are several people chatting, I try to farm, collect,any thing it kicks me to a blank page with a question mark circled. I keep the computer defragged, history clear etc.. nothing seesms to work what can I do I havae lost a lot of crops because I could not harvest them and after several hours getting kicked off every few seconds I just qiut. Any answers?

Easiest way to contact Zynga support is via https://www.zyngaplayersupport.com/ click your game; then on right hand side there's a red "?Get Help" click on this then either mail them or use chat.

Try downloading a new web browser like google chrome.

or maybe firefox

If you can, go to the support pages for Zynga's Farmville and see if you are able to go to the live chat option. I've had similar problems when I use to play Farmville. The live chat representative always solved the problem, and they even gave me more farm bucks than what I had to when trying to resolve the problem.

Go to tools on your internet page ( upper left hand corner normally). Click on options and clear cookies. AND/OR restart your computer.

Have you tried switching which farm you're on? You can travel between several farms and usually the new one becomes the default for some people. In the top right corner there should be a spot that says Haunter Hollow that has a message sign on the left of it and a globe on the right. If you click this it should let you switch between farm worlds. Otherwise at the bottom of the farm screen there's a spot that says support they might be able to help you more. As far as it not letting you visit other people report the problem to zynga they have had several errors lately they're tryng to get fixed

I can get into Farmville but not into my Farm. Crops are ready to harvest now. This has happened several times.
Please advise.

There has actually been a legitimate problem with Farmville. If you visit a farm, it loads the farm into your computer's RAM. When you visit another farm, it load the second farm into your RAM without dumping the first. By the time you've browsed around, you RAM is full and your computer has slowed to a dead crawl. Supposedly, they've fixed this. Try restarting your computer, and see if that helps at all.

Just got onto mine and its fine.

sometimes it is very slow to open - watch the bar at the bottom where it says loading below the main farmville logo and when it finished - then your farm will appear - sometimes it takes 2-3 minutes if the servers are busy or you are on a slow connection

just try to add new between apps and facebook on the url.
so it lokks like http://apps.new.facebook.com/onthefarm

it works for me... good luck
