I can get a static PDF from Acrobat to be viewed and edited in a browser but I cannot get the updated form I needed to make to be viewable, I simply get this error:
I can't do anything to my browser because it is a base form that numerous people will be editing constantly, so is there any way around the error?
Is there anything I can do to my PDF or how I could create a flowable PDF that can be viewed and edited in a browser?
Not going to happen unless the browser uses Adobe technology. As Chrome and FireFox have rejected this, so user's choices have become limited. I recommend you tell people they must download (and explain how). Also consider what you will say to the 50%+ of users using an iPhone, Android phone or iPad, who will not be able to use your form at all.
