Waiting

Hi,

I installed GP and GP premium on a clients site with all the plugins i usualy install.the
Now this site seems to not load all CSS, and is in a constant waiting mode.
It looks like 95% of the site is loaded and the site display "waiting on api.webtest.net" and this can last for 30 minutes. I am out of ideas because on a site with exact the same configuration as far as theme and plugins are concerned this does not occur and i copied all GP settings from this site.

I suspected it to be a hosting problem, but he denies this and points to theme and plugin developers.

Do you have any idea

Thanks in advance,

John
