I am having ongoing issue with my blog. I believe I had a plugin installed in the past that create a robots.txt file. The plugin is gone and webmaster tools can't locate my robots.txt file. I have tried to manually place a robots.txt file in the mydomain/robots.txt and mydomain/blog/robots.txt both ways not found. When I try to run the path myself I am getting 404 error (I am sure the file is there) (as if template is being applied to the address).
Hope you can help.
Many thanks,
[edit] I have tried other plug-ins with no effect...
