Page or Post: Cannot be displayed

Hello there, I run a site called callelatina.no. At the moment I only have a maintenance mode running, as that will hide my problem – but only for a few days as we intend to open it for the public on November 1st. My ISP is a well known actor in the Norwegian market, Netpower AS.

My problem is that I can access all parts of my blog, where I have Twenty Thirteen installed. I had some initial problems with uploading images, but after having fiddled with the folders rights in Filezilla I managed to upload them.

But one thing I cannot do, it to open a page or a post. Whenever I try to do so, I only get “Not Found. The requested document was not found on this server. Web Server at callelatina.no.”

But I can open the document in the editor, as well as the page. I can type new text, add images etc. and I can publish the updates. I can even create new pages and publish them. Still they won’t display.

My suspicion is the poor information I have had from my ISP, that I put into the wp-config.php.

/** The name of the database for WordPress */
define(‘DB_NAME’, ‘I have created a database’);

/** MySQL database username */
define(‘DB_USER’, ‘I have created a database user’);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘The password works’);

/** MySQL hostname */
define(‘DB_HOST’, ‘localhost’);

This part is where I question the information I was given. First I entered an IP-address, but the support people told me that I should rather enter “localhost.”

Does anyone have an opinion whether this may be what is wrong? Or may it be that this whole thing is nothing more than a setting in the dashboard?

I know I may be asking silly questions, but as I do this once every second year I can’t remember them all … hope someone can help me.

Regards,

Bent, Norway
