Not only is the code complex, there are 2 components of the total package that are not in your control if you have a web hosting service, the code processor and the database. If either are updated, you may have problems with compatibility and things start breaking. In dealing with hardware and software for almost 20 years, I too know first hand how hard it can be to keep up with all the pieces of the puzzle.
Way to go Angie, keep up the good work! I would say that with the season over, we all could be patient and let you fix it right and not hurry to “band aid” these problems.
