Last week, I determined that the presence of a link tag with an empty @href attribute was causing the Xenu Link Sleuth to report a non-existent broken link on every page of the WS site. We narrowed this down to an error in the assets/blocks/layout/site-scripts block, which had been left with a placeholder "thesite" instead of the actual path.

Trying to correct this myself failed; it seemed to "take", but then it appeared that nothing had been saved and the audit trail showed that the file had not been edited. Reported this, and DW called; he made the change, but bequeathed the tip that when saving you should uncheck the "Tidy HTML" checkbox. I tried this on History, which also has the same problem; the result was success, but with a minor side-effect: suddenly the History site acquired the "Food" header appropriate to Food Services. I wasn't exactly sure where this had come from, but just in case, I commented out the entire content of the site-styles.css file (which is unnecessary anyway), and republished the site. It now seems to be working correctly.
