I have just used a ‘Website Auditor’ and it came up with the following problems: Resources with 4xx status code www.addtoany.com/add_to/pinterest?linkurl=http://colinwallacephotography.co.uk/mainline-steam/&linkname=Mainline Steam It showed 9 of the above. I use the Wordpress Plugin ‘Add to Any’ on all my pages. Why is this a problem and how do I fix it? Thank you.
What website auditor are you using? If the site is functioning properly, meaning your sharing tool is working, then there isn't an issue. The addtoany.com website could be blocking your particular auditing tool. Many times I find false errors that I exclude or hide from a report when I confirm all is well. Hope that helps. Cheers!
