There's a reason this plugin has a high number of poor reviews. It doesn't work and the devs didn't provide support. They did nothing! I have all the emails to back up my statements.
Ruel and Dean were provided the exact information of what wasn't working. Instead of troubleshooting it, all Ruel did was turn the plugin on (I had deactivated when it wasn't working) and said it was fine, when it wasn't. They didn't even bother to look at the specific information they were given on what wasn't working. Instead, I was subjected to multiple emails of a highly hostile nature from Dean. That is exactly what lackluster is, and they are deserving of the feedback. It's fair, and it's honest. But Dean doesn't want people to be honest, and conceded to being entirely unprofessional.
Instead of actually looking into what the exact issue was, after being given all the information, he spent time which could have been used for actual support to instead act childish and refusing any support at all, attempting to blame me when they had all the information.
I ultimately had to change the password for the login he was given to prevent them from engaging in unethical practices or carrying out any intents to cause harm to the site. I felt it was necessary given his unstable emotional state, represented in the (non)support responses. At the same time I changed the login, I also uninstalled the non-working plugin. That was 14 hours before his last email conceding to his unprofessional behavior. I chose to use WPMU instead. It's stable and it works.
They're running quite a racket with their claim the plugin works with any theme. It doesn't. They also divert support from the forum to ZenDesk, undoubtedly in an attempt to skew public perceptions of their support and plugin's performance.
I have all the emails which documents they were given all the information, and it also documents they did nothing. There was no support. If there actually had been, this would be a non-issue.
These guys rank up there with the worst devs ever, and they got told so. I don't tolerate that kind of decorum from my 12 yr old.
