module page errors

[mobilebarn]

hi guys i am a complete newbie, i thought i was doing ok, but now when i click on the modules page from the backend i get this error msg

 

"Notice on line 136 in file /home/mobileba/public_html/tools/smarty/sysplugins/smarty_internal_templatebase.php(157) : eval()'d code

[8] Undefined property: stdClass::$price   

 

im assuming its something to do with smarty in the advanced parameters>performance section. i have tried turning smarty cache off but it does not help??

 

any ideas?

 

thanks

 

UPDATE: i just noticed in advanced parameters>config info there seems to be some missing files? not sure how i have missing files or what i might have done but pretty sure this is the root cause of the error msgs maybe? heres a screenshot

 

 

if anyone could advise me on how to get these files back as i dont want to start all over again, ive put too many hours into getting this site up, i would REALLY appreciate it!!! cheers folks
