Email configuration do not want to be saved

Hello,

I am new user of ProjeQtor and i think i miss something in my setting.

When i try to configure Email in "global paramaters"
1) I register : the smtp server : smtp.gmail.com , the smtp port : 465 or 587 ...
2) I save and i have the message " paramaters saved "
3) but my change are not taking in consideration , if i go on an other page and i come back it is still smtp server : localhost , port : 25

Even when I save and try to send a mail test i have the message : SMTP connect() failed. github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
Then i go to the log file to see what happened, and it is still " localhost/25 " as following :

2018-12-19 14:11:36.942 ***** ERROR ***** [V7.2.7] SMTP Server : localhost
2018-12-19 14:11:36.944 ***** ERROR ***** [V7.2.7] SMTP Port : 25

2018-12-19 14:11:36.947 ***** ERROR ***** [V7.2.7] PHPMail debug :

Can you help me ?
Thank you very much

Thank you very much it works.

The only one issue is that even if i delete it on paramaters.php , i cannot change some "global paramaters" it in the system , only in this file.
Is it normal ?
