1st few times I tried it said "no thread specified please contact admin if you think this is in error" But I was pressing enter not clicking the "delete" submit button...(ie6) When I tried it by pressing the actual delete submit button I got Hope this helps.
Cannot replicate the php error. However do this exactly: Create a reply to this thread. Edit > delete > leave comment > press enter I get Actually pressing the delete submit button worked this time.
Yeah... the "Enter" thing is a browser focus issue unfortunately, so not a lot can be done about it since you can't tell the browser which form to focus on. http://www.vbulletin.com/forum/bugs35.php?do=view&bugid=895
Actually that makes a whole lot of sense. Using php I was checking if a form had been submitted. <input type="submit" name="submitbutton" value="go"> then using php doing if ($submitbutton="go"){ //the form has been submitted } however it didn't work if the user pressed enter. Frustrating. I'd imagine most people are like me, and lazy using enter...
