WordPress MU

This errors had affecting the whole system of wpmu installation on my site

1. the <!--more--> tag cannot work
everytime i make a post with more tag its only give me links like this http://www.nimbrung.net/#more69

2. links on title post is not work
everytime i make a post when i try to click on title post its will take me back to the site http://www.nimbrung.net

anyone can give me solution why this problems occured
i had try to search on this forum but got nothing also try to search on google too but got nothing too :(

I think its because a plugin but i dont know which plugin make permalink and more tag not work

just want to give you all to know the plugins i had use

additional_upload_tabs.php dashboardswitcher.php misc.php switch.php
admin_ads.php delete-blog.php pluggable.php widget_widgetbox.php
admin_message.php ds_add_users_widget.php premium-blog.php wpmu-signup-captcha.php
blog_activity.php global-categories.php private_blog.php wpmu_for_dummies.php
bullet_arrow_down.gif invite.php signup_question.php wpmufeed.php
comments-tracker.php mass_mailer.php signup_tos.php

Please don't double post. The title just sending you back to the main site URL, it's not a plugin issue, most likely a theme issue. Make sure you the <h2> in the index reads something like:

<h2><a href="<?php the_permalink() ?>" title="Permalink"><?php the_title(); ?></a></h2>

As far as the <!--more--> tag throwing up tags, it might be a plugin issue, but I don't see a pluggin that would do that, so it might be another theme issue.

yep sorry for double posting

im already checking on my theme file and the code you had wrote is already on there

<h2>" rel="bookmark" title="<?php _e('Permanent Link to','andreas09'); ?> <?php the_title(); ?>"><?php the_title(); ?></h2>

and its not about theme because im not changing the theme code
you can see some of the site below they produce same error also

http://media.nimbrung.net
http://attoz.nimbrung.net/
http://wordpress.nimbrung.net/
http://iniaku.nimbrung.net/
http://kingcobra.nimbrung.net/

then try to click the title of the post and you will be taken back to http://nimbrung.net

it has affecting whole system of wpmu i had installed

Standard wordpress debugging: Remove the plugins and see if the issue still exists. If it disappears, replace one plugin at a time to see which one is causing the issue.

and its not about theme because im not changing the theme code

You will quickly discover that many wordpress themes are broken and cause issues.

errors fixed

its because im editing link-template.php
