Site gone...error in script

[resty120446]

Hello guys. I think I have messed my site a little. I was installing a component called AvReloaded, when... I don't know what happened. There was an error installing the component, as per the message after the failed installed. When I tried to visit my site, it gave me an error:

Illegal variable _files or _env or _get or _post or _cookie or _server or _session or globals passed to script.

Can anyone please tell me what went wrong?

Please help!!!!

Your front page loads for me right now.

But your SEO links don't seem to work. I suggest you turn them off, check the site, and then turn them back on.

Hi, sir! Thank you for the prompt reply. Yeah, I did your suggestion and I saw the front end loading, but when I tried to log on as user, I got the same error. But this time, I can log on at the admin/back end. Tried again after a few hours and the site was working well, including the pages. But now I am getting the same error again. Please help!
