The skin ad is active. I see it both in homepage and in the posts.
Please note it’s a script, not a background image.

I don’t see the ad in the header too. Maybe you have adblock or something like that enable?

I added the !important tag but nothing changed.
Here’s the URL: http://www.gamesprincess.it/

It doesn’t seem to work.

Can it be a skin ad problem?

I’m trying to reduce the white frame too but the code doesn’t work.
Any suggestion?

Ok, I think I finally solved the problem.
I looked at the error log and find an “out of memory” error.
I changed the wp.config file and added

define( 'WP_MEMORY_LIMIT', '256M' );

It seems to work.

I deactived all the plugin but with no success.
In the System Status panel I found this:
SUHOSIN is installed – it may cause problems with saving the theme panel if it’s not properly configured

Could it be the problem? What is SUHOSIN and how can I solve this?

I’m a little skeptical. I mean, I use the very same plugin on both my website with the same settings. One website is fine,the other keeps deactivating.

Anyway I will try to disable the plugin as you suggested.

In the error log in the public folder I got this

Thanks for your help guys.
I decided to build the Authors Page using block to include easily social media, description and a bigger photos.

@Alin thanks to you I solve the avatar problem 🙂

Thanks Lucian.
Now I’m able to exclude users (I didn’t understand that “ID” was a number, not the user name :D).

I’m still not able to see authors avatars in the list. Any suggestions?

Can you recommed a plugin able to do the job?
I would like something similar to what we have now on the website (http://www.gamesprincess.it/about/#redazione) with name, description and social networks.
