Problem adding new locale / Resaving matrix blocks Failed / Table 'matrixcontent_files' doesn't exist I've got an error message from my craft (2.6.2990) after adding a German locale: 


  Resaving all localizable elements: Failed
  
  Resaving matrix blocks: Failed 


in the sidebar and here is what I found in craft logs:

2017/09/20 14:52:13 [error] [system.db.CDbCommand] CDbCommand::fetchAll() failed: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'zg_blike.craft_matrixcontent_files' doesn't exist. The SQL statement executed was: SELECT `elements`.`id`, `elements`.`type`, `elements`.`enabled`, `elements`.`archived`, `elements`.`dateCreated`, `elements`.`dateUpdated`, `elements_i18n`.`slug`, `elements_i18n`.`uri`, `elements_i18n`.`enabled` AS `localeEnabled`, `content`.`id` AS `contentId`, `matrixblocks`.`fieldId`, `matrixblocks`.`ownerId`, `matrixblocks`.`ownerLocale`, `matrixblocks`.`typeId`, `matrixblocks`.`sortOrder`


I checked the DB and of course did not find table called craft_matrixcontent_files, instead only craft_matrixcontent_file

Any ideas?
I had a field called files, it did not belong to matrix. After deleting it (tried also simply renaming), the problem disappeared.

After that I created a field with the same name and that did not cause any problems.

Still do not know the exact reason, but later will have time dig a bit deeper, so if get some results will post them.
