Error 500

Hi there,

My site (http://evetools.altervista.org/) has been intermittently down since yesterday, reporting Error 500:
"An error occurred.

If the problem persists, probably the application you use does not work correctly, because someone is working on it, or because there is a problem in the application. In the latter case contact us."

Are there any problems I should fix on my end?

So it looks like the site works *exceedingly* slow, so some pages are not even loading and it throws this Error 500 page when this happens. Other pages that are not as busy load fine, but it takes them x100 times longer to load.

Do you have PHP scripts which make external network requests?

Yes, I've got some curl requests

That may cause the problem, could you try to bypass them? The remote host may respond slowly and causing the timeout of the PHP script.

The remote host doesn't respond slowly. Even pages where I do not access any remote hose are exceedingly slow.
