pay pal express checkout button not working

[carlos1234567]

hi,

 

i have installed presta and everything was working fine, i then installed pay pal module the official one and configured the module to accept my API details, configure the pay pal to allow the use of the express checkout on the product page and also the checkout..

 

the issue is when i hover over the express checkout button the icon changes like its linked then when you actually click on it nothing happens i have tried everything and even look at the code and i am unable to find any solution i have uninstalled the module and reinstall it and also re inputted the API details the final checkout button on the very last page of the checkout process works brilliant just the express button nothing is linked and i cant understand why

 

many thanks and hope someone can help
