I think that you too much asking in various topics.
So. Asking one-by-one until fix your issue and then asking else after that.
ya bro after php update so many error are there and email not receiving error from start try to solve all my problems as you are the owner.
What's you mean 'update'?. As default, Kloxo-MR 6.5 using php 5.3 and Kloxo-MR 7.0 using 5.4 as 'default' php branch. No update for this php version.
In many situation, change php branch from 5.3 to higher php version may trouble because possible have many conflicts between packages. So, that why I am introduce 'multiple php' in Kloxo-MR 7.0 for resolve this situations (many conflicts)
