Errors on startup of jahia

Error: internal error: failed to read custom node type definitions stored in /nodetypes/custom_nodetypes.xml

Cause

Solution

Do steps from https://jira.jahia.org/browse/JKB-29
But the customer doesn't understand it well so I send them to follow steps:

• stop the server
• try to execute the following command in the database: 

  select * from jr_fsg_fsentry where fsentry_path='/nodetypes' and fsentry_name='custom_nodetypes.xml';

• if you have a result drop this line from DB: 

  delete from jr_fsg_fsentry where fsentry_path='/nodetypes' and fsentry_name='custom_nodetypes.xml';

• flush the jahia_nodetypes_provider table: 

  delete from jahia_nodetypes_provider;

• flush the content of the directory digital-factory-data/bundles-deployed/
• restart the node
