From ACP->Forums click in Forum moderators in the left side.

1) Make the site name empty

Read my earlier post here.

how to change the default yourdomain.com site name

This is not good way as sitename value is used on other places also so avoid it.

2) This should be the correct way

From ACP->Styles->Templates

Select your template and edit the overall_header.html file

Search for the line

<h1>{SITENAME}</h1>

And comment it

<!– <h1>{SITENAME}</h1> –>

To change this value to be your site name do followings

From ACP go to General->Board Settings

Change the Site name:  value to be your site name

Also you can change the brief description of the site from Site description:

After creating forum you need to set proper permissions for the forums to be displayed.  First you need to set Global Permissions.

ACP->Forums->Group Forum Permissions (Last menu link in the left column)

Once you have selected that you will see Look up usergroup: drop down menu, select the Registered Users from the drop down menu and click submit.

From next page select the Forum and click Submit

From the next page you need to assign the desired permissions.

Select the Forum Permissions from the  Permission Type

Then select the desired permissions.

If you are not too sure what they mean then select Standard

By defaul the logo is

styles/prosilver/imageset/site_logo.gif

If you have modified the style then search for the logo in that style folder.

Simply replace this logo with your logo keep the name same and size.

Solution 2:

In Admin panel -> Styles -> Templates

Click on the Edit against your default template

Select the overall_header.html file from drop down menu

Search for this line

<a href=”{U_INDEX}” title=”{L_INDEX}” id=”logo”>{SITE_LOGO_IMG}< / a >

And replace the tags as per your requirements.

P.S. I’ve given extra spaces in tags so don’t copy and paste above line to search.

Solution 3: Replace it from Admin panel

ACP->Styles->Imagesets

Edit your imageset (by default it would be  subsilver2)

From there you can specify the logo image.
