I own the website www.vargbloom.com I have uploaded the verification page in my website
but still it shows an error like We weren't able to verify your site: http://vargbloom.com/
can anyone help
Make sure that you uploaded the right html file. If you have multiple google accounts upload file for that particular account.
You can also try alternative verifying methods like TXT, CNAME Etc.
It is also possible that some .htaccess file is blocking the read access for that file. I faced a similar problem, when the site was actually compromised and the .htaccess was modified.
