Whenever I am trying to open my site http://heat-pump-prices.net/, the site opens fine but when I'm trying to open any others page the URL shows up in the address bar as http://heat-pump-prices.net/contact-us#.Ty5X-FxcfLk I tried to add new .htaccess file and also tried to find any issue in header area but...!!! Please some one help...
It has nothing to do with the header. It's either in your permalinks settings, htaccess file, or some plug in your are running. I'd probably back up my htaccess, delete what's there and install the standard WordPress file: http://codex.wordpress.org/Using_Permalinks#Creating_and_editing_.28.htaccess.29
I've no idea about it I tried lots of thing to fix it up but no good luck to get it done perfectly! So, I just remove/upload everything to my server again! but maybe you're right, maybe it was for any plugins, because htaccess/peramlink setting was perfect.
these client are using lot's of unknown plugins but he is not so skilled! always making me confused by doing silly things but he is one of my best/regular client, and I love to make him happy by fixing those silly things
