Site gone, only error announcement - who can help???

[Edida]

Can anyone tell me why my site now just shows:

string(113) "Smarty error: [in template:32 line 18]: [plugin] unknown tag - 'global_content' (core.load_plugins.php, line 123)" string(104) "Smarty error: [in template:32 line 18]: [plugin] unknown tag - 'title' (core.load_plugins.php, line 123)" string(107) "Smarty error: [in template:32 line 19]: [plugin] unknown tag - 'metadata' (core.load_plugins.php, line 123)" string(109) "Smarty error: [in template:32 line 20]: [plugin] unknown tag - 'stylesheet' (core.load_plugins.php, line 123)" string(106) "Smarty error: [in template:32 line 76]: [plugin] unknown tag - 'content' (core.load_plugins.php, line 123)"

I'm no pro, but always willing to learn.

check that plugin directory is there (and its intact)

check all paths in config.php

did you (or your hosting company) change anything before this error occurred?

[Edida]

The plugindir is  there. How can I check wether it's in tact or not?

I see this in config.php

---

#Document root as seen from the webserver.  No slash at the end
#e.g. http://blah.com
$config['root_url'] = 'http://83.98.146.8/~bosch/cms-deTimp';

#Path to document root. This should be the directory this file is in.
#e.g. /var/www/localhost
$config['root_path'] = '/home/bosch/domains/boschspace.nl/public_html/cms-deTimp';

#Name of the admin directory
$config['admin_dir'] = 'admin';

#Where do previews get stored temporarily?  It defaults to tmp/cache.
$config['previews_path'] = '/home/bosch/domains/boschspace.nl/public_html/cms-deTimp/tmp/cache';

#Where are uploaded files put?  This defaults to uploads.
$config['uploads_path'] = '/home/bosch/domains/boschspace.nl/public_html/cms-deTimp/uploads';

#Where is the url to this uploads directory?
$config['uploads_url'] = 'http://83.98.146.8/~bosch/cms-deTimp/uploads';

---

Should there be something like the path $config['uploads_path'] = '/home/bosch/domains/boschspace.nl/public_html/cms-deTimp/plugins';?

I did not change anything, I realy don't know if my hosting comagny did.

Thanks in advance for helping me more

and are those paths correct?

if your hosting company has for example changed your site location those paths might have changed.

double check all paths.

[Edida]

Well, you were (of course) so right 

Because of a highjack of our first domain boschspace.nl, our domainname was changed into boschspace.com.

I changed all the URL's and it works again.

I could also change the URL's in my sons CMS and now his site works again too. 

Thank you very much for puting me into the right direction.
