[SOLVED] Cannot update SMTP parameters

Hello,

I am facing an issue when trying to update SMTP parameters. When I input new parameters and save them everything seems to be ok.
But if I refresh parameters page, the old values come up. Only fieldssmtp login name and password are correctly updated but all other fields related to smtp configuration (email of administrator, 'from' email when sending mails, 'reply to' email when sending mails, smtp server and smtp port) are not updated.

What is really weird is that I checked database and found that values for these fields are correctly updated here.
I tried to clear my browser cache, use a different browser, restart apache service, clear apache cache and reboot server completely but still have this issue.

I am running out of ideas here. What am I missing?

I am running ProjeQtor 6.0.2 on a raspbian server with LAMP (PHP Version 5.6.22-0+deb8u1).

I cleaned parameters.php file (there was other parameters such as LDAP configuration) and kept only DB and log parameters and it works perfectly now.

Thanks a lot for your prompt answer !
