Try disabling all your plugins and switch to the default theme temporarily, then try it again. Perhaps one of those is not agreeing with PHP5?

Start a new topic (you’ll not get as many eyeballs reading an already Resolved topic). Post a copy of your .htaccess when you do.

How have you generated your sitemap? Have you specified the correct URL as your sitemap in webmaster tools?

I see a little black box thing with a sort of horizontal line on it.

Sure it’s not just cached in your browser?

Use a plugin for the contact form. For instance:

Admin > Links might be of use for your other question.

What are you adding into your .htaccess?

AddHandler x-mapp-php5 .php
AddType x-mapp-php5 .php

Download a fresh copy of wordpress and unzip it.

FTP to your site, then delete and re-upload the wp-admin and wp-includes folders.

Sounds like you’ve been hacked. Bit of reading for you:

Sure you’ve got the right IP address?

You can try blocking it with your .htaccess:

order allow,deny
deny from 213.5.71.12
allow from all

As for wp-ban, perhaps you could try the authors forum for that? (although it does look like he’s no longer updating it)

Read this carefully, then pick one of the methods to change it back:

Could be a bad mod_security rule getting a bit confused into thinking that those words are dodgy SQL. I’d speak to the host to see what they say about it.

I expect there’s a cunning way to do that through .htaccess, ie checking the users IP address and doing a rewriterule on images, so it might be worth doing a bit of Googling to find some code you can adapt.

Alternatively, perhaps these plugins might be worth looking at:

https://www.ads-software.com/extend/plugins/country-filter/
(if they work with the latest version of WordPress)

Depends where you’ve installed it (ie if you’ve given WordPress its own directory etc), but it’ll usually be something like:
https://www.yourdomain.com/wp-admin/
https://www.yourdomain.com/blog/wp-admin/
https://www.yourdomain.com/wordpress/wp-admin/
