"Disk quota exceeded" says it all really. You've run out of space on your hosting account. Either you need to clear out any unwanted files, or you need to pay your hosting company for more space. You could also try clearing the cache, too, since this can use a fair bit of space up.

Thanks for your answer :) I´m a little bit confused because the web hosting says: "Free unlimited web hosting" and cpanel shows that i´m using almost 200Mg by this time... and other error that i´m getting from time to time from the host server is "traffic exceeded", could be that there is "something" connecting to "something" and affecting my resources?

Oh... and i have "disconnect" from my site some concrete5 blocks and themes that i´m not using right now, not all of them but some...

A times, hosting companies don't set your account up correctly. Even though you signed up to that deal, they might not have told your cpanel account that it can do that.

Contact the hosting company and they should be able to fix it for you.

If you do multiple websites for clients, I recommend buying a reseller account if you are not familiar with setting up servers etc. That way you get a "boss account cpanel" that you can make lots of other smaller cpanel packages in for your clients.

I use these guys, they have Australian and United States data centres and are really helpful - you call them and you get straight through to someone (not a machine) and thye know what they are talking about.

I used another Australian Hosting Company that was cheap, but it was really slow to run C5 sites. Crucial do a great job and my sites run considerably quicker.

Go for Cloud R2 - it's $59 a month and you can put up to 30 clients websites on it - charge them a hosting fee of even $15 - $20 a month and it's paid for. It's easy to upgrade if you get bigger too.

Thanks for the advise Patrick, i´ll see what i can do about it :)
