After conducting some changes, (like SMTP) and all, we got this error:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at firstname.lastname@example.org to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
I looked at the log and was able to only see this abnormality:
2017-02-06 07:28:23 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
I can also get the logs from the server but I hope you can help me fix this issue.
