I get a "failed to publish to to web at path .../publish/web//project.htm. Make sure folder is accessible and that the file is not locked." when I try to publish. It doesn't seem to matter where I try to publish to, I get the same error. Perhaps it is the "//", I am not sure why it adds in the extra slash, but I am guessing that could be the issue? I have tried both the default directory suggestion and my desktop etc. Any suggestions?
I just tried taking my file (which was a .htm) and doing a save As to a (.html). It now let's me pubish it.... perhaps some glitch in the .htm file format?
Also encountered this issue, and also solved my problem by resaving the main file with an ".html" extension. Stupid bug, but brilliant bit of lateral thinking on your part… not sure that ever would have occurred to me. Thanks.
