If i was you i would change the background or at least make the background more of a gradient.
Furthermore i would also upload the logo in a higher quality

If i was you i would change the header and the mailing list widget. The green is too bright and over powering ??

Hey,
Thanks for your in depth advice ??
i am going to work through each one of these within the next few days to get everything fixed up ??
Thanks again

Try clearing your browsers cache and browsing data.
In Chrome go into settings then go into history then click clear browsing data and make sure the cache and cookies are cleared and then re-open Chrome and the problem should be solved

you could try looking in your themes folder which will be in WP- Content. As well as this have a look in the Header.php file ( you can do this in FTP or by going to appearance then editor in WordPress) and see if you can find anything linking to a Favicon.ico file. THe part of the HTML may look soemthing like this <link rel="shortcut icon" href="<?php bloginfo('stylesheet_directory'); ?>/favicon.ico" />

Your Favicon will be on your servers public root directory. Use an FTP client to log in and it will be called Favicon.ico

If you want to add another Favicon then you may want to check this old and not very detailed post i published about creating a Favicon and uploading it without a plugin but basically you need a 16px image in an icon file type on your root directory.

If you have anymore questions then let me know ??

I like this ?? I like the color scheme that you are using as it makes the register button stand out. The social media buttons at the top are also a nice idea.
