I did not mean the permission of the .htaccess file, I was referring to an instruction given to the web server in an .htaccess file. There can also be more than one .htaccess files, e.g. on the web space account level, the domain document root level and in any descending directories along that tree. If you pay close attention to what exactly is being blocked, which file or directory as that is mentioned in the log files, you'll probably find the reason for that restriction.
