Slimstat errors: “cannot redeclare” & “call to undefined function”

Hi

My host’s server broke down and they moved my WP-stuff (WP 1.5.2) onto another server…and ShortStat have now stopped working:

“Fatal error: Cannot access empty property in D:\Domains\madsenblog.dk\wwwroot\wp-content\plugins\wp-shortstat.php on line 771”

…line 771 reads something like this:

“<tr><td colspan=”2″ class=”accent”>Since <?php echo gmdate(“g:i”

I then tried SlimStat, but that doesn’t work either…Slimstat tell’s me that:

“Fatal error: Cannot redeclare wp_slimstat_add_tab() (previously declared in D:\Domains\madsenblog.dk\wwwroot\wp-content\plugins\wp-slimstat\wp-slimstat.php:3381) in D:\Domains\madsenblog.dk\wwwroot\wp-content\plugins\wp-slimstat\wp-slimstat.php on line 3385

Fatal error: Call to undefined function is_user_logged_in() in D:\Domains\madsenblog.dk\wwwroot\wp-content\plugins\wp-slimstat\wp-slimstat.php on line 821″

Line 3385 reads:

“add_submenu_page( ‘index.php’, ‘SlimStat’, ‘SlimStat’, 1, __FILE__, array(“

and line 821 reads:

“// Test if user is admin, only get userinfo, when user is logged in
if ( is_user_logged_in() ) {“

Any idea what’s causing the problems?! Please forgive me, but I know absolutely NADA ’bout php and I’m not quite sure what information you need.

Hope you can help!
