If you believe that your server is being attacked by a DDoS attempt, you would want to contact your hosting provider for your options in blocking these attacks or IP ranges from accessing your server.

To resolve the error you're encountering, you may wish to disable all third party applications/plugins and switch to an unmodified theme.

[ntrivilino@alice.it]

the problem is not on third party applications/plugins or theme: problem is in the high number access to the index.php file! If i rename index.php to another file name, all return to the normality. 

[Randy Calvert]

You do realize that’s because literally everything that could be breaking your site such as themes or third party plugins can’t work?  If you rename that file… the software is essentially useless. 

If you think it’s truly a DDoS attack, you need to work with your host to mitigate it. But your test for third party resources or themes is flawed because renaming that file basically disables those along with everything else by breaking the full software.

is it possible to rename the index file (so that it is no longer found by attacks), for example index2.php, but still make the site work? what should I change?

It would take some server configuration and potentially break areas of the site plus be outside our scope of support. I wouldn't recommend it because it's a decent amount of work for a short-lived breath of freedom as the attackers will find it again.

The best solution would be to simply block the incoming attackers at the network/server level via a firewall or advanced WAF.
