Theme deactivated

Hello guys,
I have a problem with the theme.

I bought two copy of Newspaper for both the websites I managed. Recently I migrate both of them and I started having problem with the theme.
Basically once a week I find the theme deactivated. It loses all the settings and ask for the activation code.

How can I solve this?

In the error log in the public folder I got this

In the admin error log I have a plugin that keeps giving error.

[02-Sep-2015 07:12:00 UTC] PHP Warning: Invalid argument supplied for foreach() in /home/zyypzwck/public_html/wp-content/plugins/monarch/monarch.php on line 5477

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.

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?

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.
