PHP/Database Error – Null for Query
-
Hello,
I have been seeing the following PHP error occurring about twice every hour since early this morning:
[01-Jan-2016 07:06:53 UTC] WordPress database error Column 'value' cannot be null for query REPLACE INTOwp_d92f01crqn_wsal_metadata(id,occurrence_id,name,value) VALUES (0, 3378, 'RevisionLink', NULL) made by wp_nav_menu_update_menu_items, wp_update_nav_menu_item, wp_update_post, wp_insert_post, do_action('post_updated'), call_user_func_array, WSAL_Sensors_Content->CheckModificationChange, WSAL_AlertManager->Trigger, WSAL_AlertManager->_CommitItem, WSAL_AlertManager->Log, WSAL_Loggers_Database->Log, WSAL_Models_Occurrence->SetMeta, WSAL_Models_Occurrence->SetMetaValue, WSAL_Models_Meta->SaveMeta, WSAL_Adapters_MySQL_ActiveRecord->SaveI’m not exactly sure what it is referring to but would gladly welcome any insight or advice! Specifically- Does this indicate a problem on our website and if so, how can it be resolved?
Thank you,
JP
