I had NGFB but since last update I had a problem:
no way of accessing configuration pages:
Returns a "page not found"
I uninstalled and re-installed it but I have not solved the problem
I found this on logs:
[12-Jun-2013 14:12:36 UTC] PHP Warning: curl_setopt() [<a href='function.curl-setopt'>function.curl-setopt</a>]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in /home/asffces/public_html/wp-content/plugins/nextgen-facebook/lib/cache.php on line 96
Many thanks for your help
