Nice of you to share your review here. Unfortunately you neglected to include that the software is open source and free. The only money the developers make is from their custom extensions and installation/development services.
As a developer you are no doubt aware that bugs are a part of software, especially community supported open source software. Bug fixes in open source depend on the community, generally fixed based on priority. The bug you raised would be a Sev3 at best in any commercial shop, it will get fixed but it isn’t a “drop everything my site doesn’t work” type problem.
(And perhaps instead of writing a blog about it you could join the open source community and contribute the fix… unless you aren’t really a developer at all…)
Perhaps you should stick with commercial packages where you buy the right to gripe when you select the software.
TastyIgniter isn’t perfect, but they do a darn good job as an open source platform to give you something to work from.
