After weeks of working ok, 3 elements with hide / show functions have stopped working. There is one element that should show on load based on a boolean value is missing. Yesterday I replaced what I considered to be the offending element and it appeared to work. Today nothing works. I have seen other posts reporting this issue and from what I have read, it appears to be a wix issue. Is there anything I can do to a) fix it and b) prevent it from happening again?
