Developer did not test for plugin compatibility

I doubt that this review will make it to the dashboard, because it is definitely a negative one, unfortunately. But I have to say that I am so very disappointed with this plugin. It’s quite obvious that the developer did not test it for compatibility with other plugins in addition to latest version of WordPress, because I had problems from day 1–serious functionality and security errors. And in order for me to troubleshoot the ongoing issues, I had to keep buying the ‘add-ins’. Everytime I paid for one add-in, another issue arose. I’m wondering if this was the idea that the developer had in mind when building this. Make it minimally functional and then have everyone pay $29 for each add in, until it ends up actually working. The options I was given was to buy the add ins or go into the php and code myself. I’ve never had so much trouble from one plugin. I have since uninstalled it because I’m worried about it crashing my site.
