Conflict with Quform/iPhorm?

I have been using the GCS plugin successfully for some time on my sites, and a good plugin it is. Some time ago I added a Quform form to a page which worked fine; however I had occasion to look at that page again recently and the form was not displaying. After many hours of trying to find the reason, when I removed the GCS widget from that page the form appeared.
I don’t know which of the plugins has faulty code but I just wanted to let anyone else know who might have the same problem what is conflicting. For me it is OK to not have the search on the page in question so not a big deal but it might be for others. I will also let Quform users know on their forum.
