I have no idea why but Google is saying all my links are returning a soft 404. Also says being bloked by robots.txt but when looking at the webmaster page I get green check mark that its good. Same thing when I use fetch it shows as good as well. I'm totally lost as to why or what is going on. Getting a reponse code 200? It has completly killed my SEO. Can anyone see where the problem is? Thank you in advanced for any help.
Try disabling the "determine option accuratelly" (Global configuration -> Tuning). This could cause 404 errors on some websites (but you would get them in the website, not in Google).
If this doesnt work rename your current .htaccess (for example to old_htaccess) and after that rename the htaccess.txt of your root folder to .htacess. This will set the original .htaccess provided by Joomla, with no rules set by the .htaccess protection feature my extension.
If this doesn't work then I'm almost sure Securitycheck Pro is not causing the issue. Anyway you can try disabling it and check if you still have the problem.
