I duplicated a Drupal site and the database from the first one to another. Of course i copied files from 1st instance to 2nd.
Now i encounter a database error when i try to add a content to the page, but ONLY content.
Full error
PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Kolumna'entity_id' nie może być null: INSERT INTO {field_data_body} (entity_type, entity_id, revision_id, bundle, delta, language, body_value, body_summary, body_format) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_8); Array ( [:db_insert_placeholder_0] => node [:db_insert_placeholder_1] => [:db_insert_placeholder_2] => [:db_insert_placeholder_3] => CONTENT TYPE I TRY TO ADD (here its podstrona) [:db_insert_placeholder_4] => 0 [:db_insert_placeholder_5] => und [:db_insert_placeholder_6] => adawdawd [:db_insert_placeholder_7] => [:db_insert_placeholder_8] => html ) in field_sql_storage_field_storage_write() (line 494 of /home/username/domains/domain/public_html/subdomain/modules/field/modules/field_sql_storage/field_sql_storage.module).
To be very precise: 1st i copied all files from 1st instance to 2nd (which is hosted on a subdomain) then i deleted the 2nd db, then i copied the 1st database with specific prefix (of course matching the installation prefix). Most interesting is the fact that i can add content types, views etc, but i cant add any content to the page cause above error prompts.
I will really appreciate any help, and thanks in advance!
