Some of our customers are having weird problems with our uniGUI software. I updated uniGUI to the latest version yesterday and at least some customers are getting AJAX-errors, duplicate entries in uniDBGrid and so on. I troubleshooted the problem with one of our customers and I asked him to clear cache or try another browser (He was using IE 11). He tried to use Chrome and everything worked as expected. One another customer cleared cache and that seemed to solve problem for her. I can't reproduce any of the errors and problem they're having so it's really difficult to fix something that doesn't seem to be broken.
Is there something I'm missing here? What can I do to to solve this issue? Is there a way to instruct clients browser to fetch all the uniGUI files again effectively refreshing them? Is this cache related at all? If not, what should I do to prevent these kind of situations in the future when I update uniGUI to new version?
