Oscommerce Database Not Updating Fields From Admin

[Guest]

All was fine until last week, and now the db won't update. Under the configuration tab, any item Itry to edit does not accept new values and leaves them blank. No error message here. Under the category tab, I can create the folder but it has no name. When adding a new product, I get this error "Warning: reset() [function.reset]: Passed variable is not an array or object oscommerce"

 

All is strange. I have not installed any contributions or made db changes in quite some time. I also have another site on PowWeb with osc installed and have no issues... strange.

 

Any help is appreciated.
