 * I’m getting this every time I try to view or download a PDF. Didn’t do much except
   try to star a custom template, but then uninstalled all, reinstalled pluign, 
   still this error.
 * mPDF error: Some data has already been output to browser, can’t send PDF file

 * This error means data is being sent to your browser before mPDF can generate 
   and send the PDF template. First, try delete the PDF_EXTENDED_TEMPLATES folder
   and reinitialise. If you still experience a problem there could be a plugin conflict.
   Deactivate all other plugins besides Gravity Forms and Gravity PDF to see if 
   the problem persists.

 * Thanks. That did work. I’ll keep my eye on it for repeats.
    Didn’t bother with
   other plugin deactivations for now, will hold that card. Appreciate the help.
