Problem with template The World

At the moment my site is too slow..

The problem is that my site keep responding with errors of different kinds, i don't know why this is happening.

I tried to do some cleaning up, deleting modules, plugins, enabling cache, and such. But it doesent help. 1/6 clicks leads to an errror.

Help and suggestions why this is happening would be nice.

Now i have deleted almost all of my modules/components, just to check if this would fix the problem. It didn't. Could the problem be in the GK AJAX? I give up.

Hi

I had no problem watching Your site. Please try to see it Yourself on other computer. It may be a problem with Your system / browser.

I haven't got as well.

Thanks for comments. It looks like the problem was with my webhost. They had some problems with their servers.
