In order to get more information about the problems, it is required to enable the Debug mode of the plugin LOG. To do this, the following steps must be followed:
Go to Configuration → System → Logging and Profiling → Configure logging level for another package
Note: If instance is restarted, this configuration is lost and the steps would have to be repeated.
When the problem is solved, remember to disable the LOG from the same configuration page by selecting OFF from the list.
