We got the copyright in 4.86, with instructions, but Carole says it changed so I'll pass this info on to her and hopefully she'll work it out in the morning.
Much appreciate your help here with our upgrade at the wee hours of Sunday morning!
Maybe you need to check this link for more info on the branding free option, but if you have that option already look in pp-inc.php around line 368
I too looked at the pp-inc.php file and am not sure what needs to be edited for the branding free version. There is code there for a print of a variable "$theader" which doesn't seem to control copyright. I also searched for the term copyright in that file and found nothing there.
Could you give me a bit more information on removing the branding. And, yes, we received e-mail confirmation of the branding free option the other day when we purchased the license.
