fix 500 error after logging in or submitting form

Hi guys, I’m new in drupal, so any help would be much appreciated.
The problem is I’m getting 500 error after logging in to the dashboard or even when trying to submit a form. After refreshing the page I’m able to access admin page.
I turned error logs on, here is what it says after form submission or admin login:
PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table ‘u4402122_prem.cache_form’ doesn’t exist: DELETE FROM {cache_form} WHERE (cid = :db_condition_placeholder_0) ; Array ( [:db_condition_placeholder_0] => form_form-cuEyw8JspffiJxm-Zx3Hk-aYSj7Gipr4C0q-nVKdZlM ) in function cache_clear_all()
I googled it a lot but couldn’t find the solution related to the premium.cache_form.. I understand that it is somehow related to the webforms module tables in the database.

Thanks a lot in advance.
