Some errors show a line number where the error became
apparent.
Just doubleclick on the filename next to the error: Presto
Now to discuss
apparent:
Something happened way back
there somewhere, like you opened a <div tag , but it never closed and we now see a </body
relative links can become broken with section splits:
1) Just avoid using the use, even if it is legit
2)REGEX search for: Text\/\# (Finds: Text/#fooeyonus. anchors without a filename)
