I just received from google console the message that there is a remarkable increase of 404 pages.
These seem to be all related with a link in the sidebar.
The sidebar appears at all my blogposts.
The link in the sidebar is that created the last increase in 404 pages is:
http://www.terratrotter.eu/tshirts (Under the heading “In the spotlights”)
Which results in the following crawlerror / 404-page:
A link like this is created for all my blogposts (since the sidebar appears at all my blogposts.)
Any idea what is generating this false links?
