I submitted my robots.txt file ages ago to Google and it is still giving me a syntax not understood for the first line.
After Googling the most common problem is Google adding a '?' at the start of the line but it isnt doing that to me.
the url to the robots.txt is
www.leisurepursuits.co.uk/robots.txt
The error is:
Line 1: User-agent: * Syntax not understood
This error shows because the expected robots.txt file format is plain text encoded in UTF-8. The file consists of records (lines) separated by CR, CR/LF or LF.
If a character encoding is not a subset of UTF-8, then your robots.txt files is being parsed incorrectly.
First check your robots.txt url in http://www.asymptoticdesign.co.uk/cgi-bin/check-url.pl by selecting the second option “view source” and see that it responds successfully or not.
Now upload your robots.txt file again. It will not show error as shown previously.
