warning

I have recently installed OA 7.x-2.15 under OpenSuse 13.1 running under Apache 2.4.6 with PHP 5.4.20 and MariaDB 5.5.33. When I setup my first news section on the front page as a test during my attempt to learn how to use OA and then jump to that URL, I get the following warning twice at the top of my screen:

Strict warning: Only variables should be passed by reference in ctools_entity_from_field_context() (line 179 of /srv/www/htdocs/oa/profiles/openatrium/modules/contrib/ctools/plugins/relationships/entity_from_field.inc).

Based on job created by user Norrwing - I would just like to warn themers and other Drupalers not to apply, since this guy cheated everybody who was involved in his projects and will most probably do the same for you.

He is currently using my code (2 themes + many other custom solutions) as a basis for his project, and I do know few other Drupal developers who had the same experience.

Hola les cuento que estoy usando drupal de bastante tiempo, y creo que ya casi olvide todo, pero bueno recordar es mas facil que volver a a prender, me cree varios contenidos y al crearlos o editarlos me aparece lo siguiente:

warning: escapeshellarg() has been disabled for security reasons in /home/softwarp/public_html/drupal/sites/all/modules/imageapi/imageapi_imagemagick.module on line 148.

When I try to gone to "phpBBforum settings" in Drupal, I get this warning: call_user_func_array(): First argument is expected to be a valid callback, 'phpbbforum_admin_settings' was given in /hsphere/local/home/drupal/ubercart.drupal.no/includes/form.inc on line 218.

I have tried to followed this guide "\phpbbforum-5.x-1.x-dev\phpbbforum\contrib\phpbbdrupal\install.xml" Waht to do now?
I'm using Drupal 5.7 and phpBB3
