May be your hosting server has loading issue problem. Site taking too much time to load. I even did not able to work. But I have fixed that lines of code through FTP. But I was not able to see the result. Can you check please and let me know.
Can you please delete your current WP Project Manager Pro and download and install a new WP Project Manager Pro. To download WP Project Manager Pro please go to your profile through this link – http://wedevs.com/account/. I have tried to install by backend admin but did not able to. After install please deactivate all other plugin except WP Project Manager Pro and see the result and let me know.
I am still working on your site. I have already forward this issue to our developer team. I have done similar fixing for you and jay. Plugin conflict can be a factor here. Jay uses light plugin but you are using weight plugin which can be make trouble. Whatever, I am still working on your site. Please have a patience. I will come back to your with a right solution very soon. Please allow me some times.
