The content form is calIed from a list. I have tried to change URLs SEF int View option for listed field without success.
"I used a free button with Seblod Print Extension" - this is a bug. On content view you can use Free text field and put print link on it.I made a pull request to fix this problem, if you apply this change print link on Button free should work too.
Thank you very much for your feedback, with this workaround the print function is ok.
have a last question, into the windows opened, button displayed into
content form are always displayed into printed form and joomla print
button displayed at the left end corner, so not easy for end user to
undestand that he does rolls donw windows to find Joomla print button.
have not found how I can hide the buttons than comes from content form
or at the lest move the Joomla print button to upper (left or right)
side of the form? perhaps into /templates/template_name/components.php ?
