Apologies if this has been answered elsewhere, my search didn't turn up something that addressed this particular situation.
An older omeka 1.2.1 site I help with has begun to throw these warnings at the top of pages:
Strict Standards: Declaration of Omeka_Acl::addRole() should be compatible with Zend_Acl::addRole($role, $parents = NULL) in /home/.../application/libraries/Omeka/Acl.php on line 18
We also see them with Declaration of Omeka_View_Helper_Url::url() and Declaration of Tag::fieldIsUnique()
Any sense for the best approach to resolving those?
