Facebook connect error

Dolphin 7.3.3 has facebook connect error. In admin panel its setting page can't be opened. While clicking on facebook connect module a blanck page opens. open social module has error too, so I have disabled it. Does any has solution ?

Can you reproduce the problem on demo.boonex.com ?

 I just checked but its workin fine there but in my admin panel it gives error.

If you have a error, report what the error is.

If all your seeing is a blank white page then that indicates a error is occurring, but your php is configured to not display them. In that case you need to look in your php error logs for the error that is occurring and report it here. Without the error, there is nothing we can do to help.

You could also enable the display_errors option in your php configuration while the site is under development. That option should be left off when you don't need it.

 Error has been detected and solved. I unisntalled the module and again when tried to re-install it gave error message "PHP 5.4 or more is required." Then I upgraded PHP version as mine was 5.3.
