What versions of the Contribution plugin and Omeka are you using?

Have you tried uninstalling and reinstalling the plugin?

i am using the Contribution-1.3-2.1.1 and version 1.3.2 of omeka.

And have you tried uninstalling and reinstalling the plugin through the admin interface (not deactivating or removing/replacing the plugin files)?

The error you're getting suggests that the Contribution plugin's tables haven't been correctly installed.

thank you that helped me out
