Hi WiseCapra
The messages in your screenshot are purely strict standard messages. You can reassuring disable those messages in your php configuration. They only should be enabled on a development enviroment anyway.
For your info: strict standard messages are introduced in php 5.0.0 and should help programmers more or less to get their code ready for futuring php versions (6.x). You can disable them in your php.ini by changing the error_reporting variables (see
here
for more information) or in your vhost definition by adding e.g.
php_admin_value error_reporting 30719
which will show everything except strict messages.
Note: it is also highly recommended to disable the displaying of error messages on production servers.
Since I also installed other components on my dev server which cause strict standard messages, I had those messages disabled and didnt realize, that my own code also causes some of them

but I will try to get rid of them in a futuring release
