I've discovered that W3 Total Cache has modified ALL outbound links in my WordPress site. You can see an example of the modified outbound links after I ran W3TC (and it attempted to make a cached copy of my links and videos):
http://honeytrek.com/southern-vietnam-getaways-muine/ (search the term "see Facebook slideshow" to go straight to a outbound link that is now broken)
That link currently points to... "http://www.honeytrek.com/wp-content/uploads/2014/01/photo.php?fbid=565879903488420&set=a.565879833488427.1073741841.137775936298821&type=3&theater" instead it should point to that page over on Facebook.com/HoneyTrek...
...respectively, but W3 Total Cache has 'updated' them, apparently trying to make them point to copies in a cache? Anyway they both 404 now, as they've been altered.
This is true for all outbound links on the site now. I've changed re-saving settings etc. in W3 Total Cache without any success. Obviously this is quite a serious problem as all my outbound links now 404 on my site (fyi, internal links all work fine).
Any idea how to revert this? Thanks.
