Initialization Error / Unable to locate database?

Hello,

After doing a site restore because a plugin breaking the entire site, it seems like WordPress cannot locate the database? When trying to edit a page, I get this error:

Array
(
    [callback] => Array
        (
            [0] => CRM_Core_Error
            [1] => simpleHandler
        )

    [code] => -18
    [message] => DB Error: no such table
    [mode] => 16
    [debug_info] => SELECT *,  config_backend, locales, locale_custom_strings
 FROM civicrm_domain 

 WHERE (  civicrm_domain.id = 1 )  

 [nativecode=1146 ** Table 'frenchf_crm.civicrm_domain' doesn't exist]
    [type] => DB_Error
    [user_info] => SELECT *,  config_backend, locales, locale_custom_strings
 FROM civicrm_domain 

 WHERE (  civicrm_domain.id = 1 )  

 [nativecode=1146 ** Table 'frenchf_crm.civicrm_domain' doesn't exist]
    [to_string] => [db_error: message="DB Error: no such table" code=-18 mode=callback callback=CRM_Core_Error::simpleHandler prefix="" info="SELECT *,  config_backend, locales, locale_custom_strings
 FROM civicrm_domain 

 WHERE (  civicrm_domain.id = 1 )  

 [nativecode=1146 ** Table 'frenchf_crm.civicrm_domain' doesn't exist]"]
)

How should I go about resolving this? Thanks!
