A joomla site is giving me this error:

> 
> Fatal error: Class 'JModelList' not found in /home/site/public\_html/administrator/components/com\_joomdoc/libraries/joomdoc/application/component/modellist.php on line 16
> 
> 
> 

I only noticed it this morning when i tried the search, The last time i worked on the site was over a month ago (Installing , removing extentions, fixing errors ....) so i can't really figure out at wich point this error surfaced. 

I read somewhere that The class JModelList is not used in Joomla 1.5 (what i'm using) .... i don't know how that could happen because i made sur that the extentions i'm using supported joomla 1.5 and i never made an upgrade.

Just in case, the line 16 of modellist.php is

```
jimport('joomla.application.component.modellist');

class JoomDOCModelList extends JModelList { ...

```

Help!

thank you.
