Can you try this one for me?

The error is because the variables aren't defined.

Installing the new V3.1 you posted today, only one error message is left -> "Notice: Undefined index: default in C:\xampp\htdocs\joomla\plugins\system\pcdtr.php on line 415"

I have a similar problem but it affects the height of certain fonts such as 'Zapfino' where certain taller characters like lowercase 'h' get partially clipped on the upper end.

In my case, I'm having trouble with an h3 header menu title. I've attached a couple of images. The blue box is not part of the styling and was generated by firebug just to outline the exact boundaries of the span.

Is there a way to fix this ?

Thanks

Without box (as appears with pcdtr styling):

Finally, how it should appear (from text editor, minus the line):



UPDATE:

I read through your 'how to' notes and realized I needed to enter the font's biggest characters in the 'test string' box for the correct size bbox. The width problem seems to be under control thanks to your last update.
