In some cases it can happen that the design results in the links being the same color as the background or close enough that they cannot be seen.

If you look in the stylemojo.css file you can find this for links in the main content:

a{color:inherit}

you may need to change that to a color that works with your design. Or to affect only the module edit links, you may need to specifiy a color in this:

a.ModuleEditLink,
a.ModuleEditLink:link,
a.ModuleEditLink:visited,
a.ModuleEditLink:hover,
a.ModuleEditLink:active { font-size:10px !important; color:yourcolor; }

or to specifically affect the top nav links like sign in you would modify this:

.sitelink,a.sitelink:link,a.sitelink:visited { color:inherit; ...

After making changes to css files, go to Administration > Advanced Tools > Design Tools > Cache Tool

and click the button to reset the skin guid

​Hope that helps,

You could change the design to use smaller font, or you could move the edit links outside of the title by editing your theme.skin file.

Look for this:

<portal:ModuleTitleControl runat="server" 
    DetectSideColumn="true"
    UseModuleHeading="false"
    Element="h2"
    SideColumnElement="h3"
    LiteralExtraTopContent="<div class='art-postmetadataheader'>"
    LiteralExtraBottomContent="</div>"
    SideColumnLiteralExtraTopContent="<div class='art-blockheader'>"
    SideColumnLiteralExtraBottomContent="</div>"
    ExtraCssClasses="art-postheader"
    SideColumnExtraCssClasses="t"
    LiteralHeadingTopWrap="<span class='art-postheadericon'>"
    LiteralHeadingBottomWrap="</span>"
    
    /> 

change it like this:

<portal:ModuleTitleControl runat="server" 
    DetectSideColumn="true"
    UseModuleHeading="false"
    Element="h2"
    SideColumnElement="h3"
    LiteralExtraTopContent="<div class='art-postmetadataheader'>"
    LiteralExtraBottomContent="</div>"
    SideColumnLiteralExtraTopContent="<div class='art-blockheader'>"
    SideColumnLiteralExtraBottomContent="</div>"
    ExtraCssClasses="art-postheader"
    SideColumnExtraCssClasses="t"
    LiteralHeadingTopWrap="<span class='art-postheadericon'>"
    LiteralHeadingBottomWrap="</span>"
    RenderEditLinksInsideHeading="false"
    /> 

That will put the edit links in a separate div below the title but may need some css tweaks to make it look good. But only editors will see that anyway.
