Hello, just to say thank you (W.P. Ginfo) for the solution above it works like magic.
The issue actually lies with the hosting company.
In my case what I learnt was that paypal have banned out going connection from my hosting company, that what happened. It has to do with the Curl script.
All my pages that has paypal express checkout on it refuse to load but when i deactivated the plugin, the pages loaded fine.
I also tested the same site on another server and it worked fine.
I will suggest that you contact your hosting company.
My hosting company up to this moment are yet to fix the issue so am having to use another provider temporarily.
Cheers
