sudden problem

my site was working just fine until i tried to install a new template. it obviously screwed something up so i deleted it through ftp, but now my site is STILL not working. I'm getting the following:

Warning: require_once(/home106b/sub003/sc63357-LJEZ/mysite.net/community/templates/tmpl_wtt/scripts/BxTemplConfig.php) [function.require-once]: failed to open stream: No such file or directory in /mounted-storage/home106b/sub003/sc63357-LJEZ/mysite.net/community/inc/params.inc.php on line 90

Fatal error: require_once() [function.require]: Failed opening required '/home106b/sub003/sc63357-LJEZ/mysite.net/community/templates/tmpl_wtt/scripts/BxTemplConfig.php' (include_path='.:/usr/share/php5/') in /mounted-storage/home106b/sub003/sc63357-LJEZ/mysite.net/community/inc/params.inc.php on line 90

Try to set in advanged the uni template as standard... sometimes this can help..

i can't access the admin panel...that same message comes up whether i'm trying to view the site or admin dashboard

Use your FTP go to:

inc/params.inc.php.

Edit line 73 $tmpl = 'wtt';

to

$tmpl = 'uni';

I download the file to my PC and edit... then upload it back to the server.  As always make a backup of files before editing.
