I finally gave up with my hosting provider. I also gave up with shared hosting alltogether. That was the last straw.

I moved the website to a rented server, and I'm going to manage it all by now. Please let me know if you have any issues with it (it should all be fine though!)

Anyway, if you're like me and can't face shared hosting companies any more, I'm looking into some scheme where I could share a server with other websites. Let me know if you could be interested and we can discuss :-)

At last, enjoy a fast website!
