I'm encountering the following error message/s relating to any Affiliate link appearing on my page using the Data Bindings SEO PHP extension when I test page as Google Bot...
Warning: DataBindings\Renderer\{closure}() [function.databindings\renderer\{closure}]: unterminated entity reference v=xxxx&q=xxxxx&r=xxxx in /home/privhire/public_html/ScriptLibrary/DataBindings/Renderer/Parser.php on line 158.
Will this error be detrimental? The error messages are not visible when viewing via browser, only when testing using the extension.
Regards, Mike.

Hello Mike,
Can you please provide a link to your page?

It's still in development. So far of utilised my new Bootstrap 3 extension from DMXzone and thrown on some includes...

This is the test page:

This is the browser page:

Cheers Mike.

Hello Mike,
When i visit your page i do not see any errors. Did you change something?

Sorry, try again... I'll leave the page alone from now on. When I last updated it dropped the SEO code altogether.

Hello Mike,
The issue on the page is caused because when setting attributes they have to be encoded and on your page they aren't. We included a check about this, i am emailing you a new php file to place in your website.

That's worked perfectly - thank you! Out of interest, how did the new parser file fix the issue even when I haven't changed anything with regard to the 'unencoded' attributes?

Long Story Short:
There is a fix included for such situations. So we check if the parameters are encoded or not and if they are not the code is different
