First issue is that the PM system only appears to Admin, I cannot see the option that allows other users to activate the PM system.
So if I try to send a PM to myself I get this:
Fatal error: Call to undefined function sp_editor_parse_codetags() in /problem-with-post-edit-buttonome/gruzcom1/public_html/ABF_Test/wp-content/plugins/simple-press/sp-api/sp-api-filters.php on line 297
Is this the correct place to report bugs by the way?
