Galaxia Workflow Engine

Galaxia Workflow Engine

Admin Processes Notice...

Not sure how to get rid of this or whether there has been some kind of mistake in setup. I get the following error at the top of the page:

Notice: Undefined variable: mid in /home/sites/my domain/public_html/tiki/lib/Galaxia/src/ProcessManager/ProcessManager.php on line 454

I've had a look at the php file and as the error say there is indeed a variable $mid and I'm not sure why it isn't getting deffined in my setup. Is there a way to fix easily or suppress this message because it's obviously quite annoying and distracting.......any help would be appreciated.
