Hello @majidmad
Sorry to here this. It might because some conflicts or JS runtime fatal error.
We really appreciate if user ask for support before posting negative reviews because wordpress plugin have to work with other plugins and different themes. No wordpress plugin can be 100% compatible with all plugins and themes.
We try to help every user having any kind of trouble and we have been having good experiences so far. We also expect users at least ask for support and then post any reviews (good or bad).
Please allow us to help you by creating a ticket on our website and we are sure you will be a happy user after that.
