The timthumb image url is giving me the following error:
A TimThumb error has occured The following error(s) occured: Could not create the index.html file - to fix this create an empty file named index.html file in the cache directory.
You can check it here: http://www.4g.co.uk/wp-content/plugins/related-posts-pro/includes/timthumb.php?ct=1&cc=FFFFFF&q=95&w=200&h=200&src=http%3A%2F%2Fwww.4g.co.uk%2Fwp-content%2Fuploads%2FLumia_930_4G_small.jpg
I suppose that timthumb needs an index.html file in the cache folder. Please try to create one with 777 permissions in the plugins/related-posts-pro/includes/cache/ folder.Best,
