This bit from gesman's link is a very good way to start sorting that out:</p> <blockquote><p>// If you want to quickly test if your activation hook works - put exit() into it. At least you'll see error during activation. </p></blockquote> http://wordpress.org/support/topic/266063#post-1226617 Sun, 27 Sep 2009 15:04:29 +0000 gesman 1226617@http://wordpress.org/support/ <p>See my post with sample of working code here:<br /> <a href="http://wordpress.org/support/topic/312342?replies=2#post-1226615" rel="nofollow">http://wordpress.org/support/topic/312342?replies=2#post-1226615</a></p> <p>Gleb </p> http://wordpress.org/support/topic/266063#post-1208591 Fri, 11 Sep 2009 19:45:11 +0000 mgtonelli 1208591@http://wordpress.org/support/ <p>got the same issue, did any of you guys found a solution or had implemented a work around to make it work???</p> <p>need to create tables on the DB, not able to do that since 'register_activation_hook' just doesn't work..</p> <p>regards.. </p> http://wordpress.org/support/topic/266063#post-1125148 Fri, 03 Jul 2009 18:47:52 +0000 lexayo 1125148@http://wordpress.org/support/ <p>me too<br /> so i do this :</p> <p>function silex_activation_hook(){<br /> .................<br /> }</p> <p>// does not work =&gt; call it directly register_activation_hook( __FILE__, 'silex_activation_hook');<br /> if ($_GET['activate'] == true)<br /> {<br /> silex_activation_hook();<br /> } </p> http://wordpress.org/support/topic/266063#post-1119324 Sun, 28 Jun 2009 12:45:56 +0000 god0fgod 1119324@http://wordpress.org/support/ <p>Oh, and the table isn't created. </p> http://wordpress.org/support/topic/266063#post-1119319 Sun, 28 Jun 2009 12:43:52 +0000 god0fgod 1119319@http://wordpress.org/support/ <p>It's the same with me.
