Dear Shawn, dear Batjoro,
while reading your initial message again, I noticed that you are using quite an outdated version of VirtueMart. You should be aware that all versions up to VirtueMart 2.0.22 contain serious security issues!

Upon further thought, that old version also explains the problem you are having: The plugin relies on a small feature that was added in newer VM versions, but is not in your version. The log error confirms this, because in newer VM versions, this very case is actually handled.
If you cannot (or don't want to) update to the latest VirtueMart version, you can manually add the corresponding three lines of code to one of the VirtueMart core files to fix the problem. In particular, in the latest VirtueMart version the file administrator/components/com_virtuemart/helpers/html.php contains the following code starting at line 85:
static function row($func,$label){
$VmHTML="VmHTML";
if (!is_array($func)) {
$func = array($VmHTML, $func);
}
$passedArgs = func_get_args();
array_shift( $passedArgs );//remove function
array_shift( $passedArgs );//remove label
...
In contrast, your version of VM contains the following code at line 70:
static function row($func,$label){
$VmHTML="VmHTML";
$passedArgs = func_get_args();
array_shift( $passedArgs );//remove function
array_shift( $passedArgs );//remove label
...
As you see, the change in newer VM versions is the added
if (!is_array($func)) {
$func = array($VmHTML, $func);
}
Simply add these lines to your VM code and the plugin should work. You don't have to worry about updates (i.e. most manual changes to the VM code would be overwritten when you update VM), because if you update your VM installation to the latest version, that version already has that code included...
I hope this helps,
Reinhold
