Hi,

I have problem with the theme on my site> http://aktuelno24.mk/ I don’t know what is causing this, but when i publish or change something on post there is blank page.

You can see on here> http://postimg.org/image/69xee2kxz/

I disabled almost all plugin but nothing is helping. I hope you can tell me what is the problem?

I have another problem, but I don’t know will you help me. Its about my hosting. My server is very busy when I am having less than 20 visitors. Maybe the first problem is causing the other.

The guys from my hosting tells me that I have script that is causing a lot of traffic, but I don’t know how to find and stop it? They sent me this> http://postimg.org/image/o254z0ffv/

Thanks in advance

Best regards

This is in my errors in cpanel, maybe will help>
