   errors mean and how I can fix them? Thanks in advance.

 * Filters and Actions are WP’s way of providing plugins a way of doing some work
   for you. When you want to “filter” content you use the “add_filter()” command
   and put in your function.
 * When you want to take an “action” based on something else, like posting, editing
   and so on, you use the “add_action()” command.
 * The remove_filter/action() do the opposite. These are basic WP functions that
   should essentially never be undefined.
 * From the looks of it, I would say that your WP installation is a little messed
   up.
 * What version of WP are you using? What have you installed/uninstalled recently?
 * Regards
