SMTP cahnges are not being saved

Hi: we have been unable to know why the SMTP account setting are not being saved.
We are trying to update the SMTP host, user and password, but any time we hit the “save” button, the parameters still remain at old settings.
We checked permissions, and read all kind of logs, but still dont have any idea what going on.
Do someone else also experiencing this error?

This is surprising. Ideally this should not happen. Have someone even done custom code in the CRM admin module?? Have you checked the CRM and apache logs while doing the update??

Well. Thanks for your interest on this.
Based on your comments, I found those errors on the suitecrm.log

Any idea about where those errors come from?

Have you done these 2 things

1: Enable SMTP at your EMAIL SERVER end??
2: Testing the Email Configuration settings before save it? If you are able to send the test email successfully, then it should also be saved.

Hi:
Even the test were fine, and I received the test message, When I hit the “save” button, I still got the old information.
Attached is the last suitecrm.log entries.
