Hi
This site is noindexed/nofollowed and as the 4SEO crawler use the same rules as Google and Bing, it does not crawl your site.
You can configure 4SEO to bypass your protection under EXCLUDE/INCLUDE PAGES on the Pages | Settings | Site analysis dialog.
Note that if you enabled "noindex,nofollow" under Joomla global configuration, 4SEO has no option in the currently stable version to bypass "nofollow". We'added an option for bypassing that in next release (which you can download from the development versions download area ).
Side note: using a global "noindex,nofollow" option is not recommended (by Google) when developing a site because it does not actually block visits. Only "nice" search engines respect it and so your content in development can still be scraped by bad robots and reproduced on their site, which can end up in Google.
They (and we) recommend using an .htaccess password protection instead, which completely blocks access to the site for all robots.
Best regards
