Hey @fcovecino,

The Firewall does need to be Optimized before it can start blocking the IPs. Take a look at the Real-Time IP Blacklist portion of this page – https://www.wordfence.com/help/firewall/options/.

What errors are you getting with SiteGround? Have you seen this article?

Please let me know.

Thanks,

Thanks for the response… yes, that’s exactly the article I’m following, but I get “Argument #2 is not an array in /…/wp-includes/load.php on line 66” (three points included by me so I don’t publish the actual path). I don’t find any way to eliminate that error, it happens as soon as I setup the variable in the php.ini file. I actually have to delete the php.ini file to get the site back online.

Hey @fcovecino,

Can you edit your php.ini file and add this line:

auto_globals_jit = off

You can also do this by going into cPanel -> PHP Variables.

Please give this a try and let me know if it helps.

Thanks,

Hello,

It worked! Now the firewall appears optimized and no errors.
Why is that it works?

Thanks

Hello,
Even if I could optimize the firewall without error by adding the additional variable, I got 17 hack attempts from a single IP address and the IP wasn’t blocked… Wordfence also keeps showing in the “today” row of hack attempts some that happened more than 24hrs ago.
Anything else I need to configure in Siteground? Maybe there are some of the SG Optimized plugin settings getting on the way? Any of the caching settings?
Again thanks for the assistance.

Hey @fcovecino,

On SiteGround servers, it appears they have auto_globals_jit enabled by default – this causes certain variables within $_SERVER to be undefined because it’s loaded later into the array (which happens after Wordfence). Setting it to off allows Wordfence to run before the code loads which the Firewall needs enable to do its job.

Thanks,

Gerroald

Thanks for the information, do you have guidance for my latest message?

Hello,

The old hack attempts went away now from the “today” statistics, will confirm if new attemtps produce IP blocks.

Best regards,

Hello,

I can confirm that everything is workiing right now, thanks for the assistance.
