Thank you Andy . But, the problem is MOZ crawler was unable to crawl the website even though the line " Allow: / " was present in the robots.txt.

User-agent: *
Allow: /
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /?color=

Hello All,

I'm facing an issue with the MOZ Crawler. Every time it crawls my website , there will be an error message saying " **Moz was unable to crawl your site on Sep 13, 2017. **Our crawler was not able to access the robots.txt file on your site. This often occurs because of a server error from the robots.txt. Although this may have been caused by a temporary outage, we recommend making sure your robots.txt file is accessible and that your network and server are working correctly. Typically errors like this should be investigated and fixed by the site webmaster. "

We changed the robots.txt file and checked it . but still the issue is not resolved.

Do let me know what went wrong and wjhat needs to be done.

Any suggestion is appreciated.

Thank you.
