I'm redesigning a greymatter site so went in and put a comment at the start and end of every template to aid debugging.
The Author Smartlink Target template was blank, and since I didn't intend to change that I went back in to remove the two comments. But rather than clear the contents of that template, every time I rebuild, the comments are back again.
I just overkeyed the comments with target="_blank" but after rebuild it's not replaced the comments with it, but appended the new text to the comments. I've been playing with this a bit more and now I have this result: <!-- Author Smartlink Target -->
Thanks to you both for your rapid suggestions. It appears if I select all, delete and rebuild I'm just appending nothing to the end of the existing content. ie what happens after a rebuild is I end up with the same old content again.
Editing the cgi directly has done the trick. I had figured that would be my fallback position granted courage and a backup ;D
Kudos Geoff, you found a bug! For some reason, the value of that textfield (Author Smartlink Target Template) was being hidden on the page, as well as having a edit box. Greymatter was squashing it all together when saving. This will be fixed in 1.7.4.
