Please go into the admin area and ensure that the unit parameter is set to something. There are still a number of new settings which are not getting properly initialized upon activation of the plugin, and if just downloading and unzipping without deactivating, deleting, and then installing the new build, I can see how a number of things might not get set in the plugin options.
It looks like the unit of measure is not being set. The first line number referenced in the error is the exception handler in tcpdf. The first hit in the stack trace refers to this bit of code:
public function setPageUnit($unit) {
$unit = strtolower($unit);
//Set scale factor
switch ($unit) {
// points
case 'px':
case 'pt': {
$this->k = 1;
break;
}
// millimeters
case 'mm': {
$this->k = $this->dpi / 25.4;
break;
}
// centimeters
case 'cm': {
$this->k = $this->dpi / 2.54;
break;
}
// inches
case 'in': {
$this->k = $this->dpi;
break;
}
// unsupported unit
default : {
$this->Error('Incorrect unit: '.$unit);
break;
}
}
I thought that I had the fallback unit set to mm, but it’s possible that during my internal testing, I left that out, expecting that the database would always have something usable set in it.
So, access settings, poke around, save, and try again. That should at least get the new settings primed into the db.
Thanks for reporting this, and good luck!
