I had posted this before also but couldn't get any satisfactory result.

I don't know why but the contact importer doesn't work well with my website. When I click on it, the importer popup window shows at the very bottom of the screen just above the footer and I had to scroll down to invite them. I don't know why this happens only on my website. I have not seen any such problem on any other website.

Please help me anyone who knows how this problem may be solved.

P.S. 

I had uninstalled and installed the plugin many times but it simply didn't work.

I tried it to work by removing all my custom CSS but it didn't

I tried to make it work in 1.4 but it didn't work and the same with 1.5

It was working fine before but now for 1 month it isn't working well!
