You need to find much better hosting service. Your application is very slow. Very often offline
It's also a very strange way of counting tasks, maybe you can add some explanation on dashboard page like how old posts are counting, when it will campaign will be finished and etc..
The application is slow due to the automatic counting of likes, comments, shares, retweets. Takes like more or less 20 requests on a single page load at a time.
However, the posts are counted for the month of the campaign. Like posts of July will be counted for July campaign.
Thanks for your review.
