hiding login link

Hi,

to hide login link I did following to modules/core/templates/blocks/local/SystemLinks.tpl

change
{if isset($theme.systemLinks[$linkId])}
to
{if isset($theme.systemLinks[$linkId]) && $linkId != 'core.Login'}

But after this, it some how effected highlighting. If I change highlight for an album, it does not show the highlight image for that album. Some default is being shown.

I try to put login link back by just removing "local" directory...but the longin does not show up.

Any leads. Thanks for the help.

Update: I could able to resolve "login" link issue by doing maintainance run on deleting templates.
But this did not resolve my highlight problem. Where should I look for this issue ? thanks.

regards
Swamy
