SMTP problem

[ Moderator note: moved to Fixing WordPress. ]

Hi,

I have a little problem, i have a website, and i use email forms with SMTP..
I installed a plugin and its up to date, its configured correctly… the plugin worked before the update from WordPress 4.7 to 4.8 i remember that i have solved the problem with a code in one of the files in WordPress.. or in the theme funtions.php file, i updated the both files when i updated WordPress and the theme… i need help to find the code that allowed the plugin to send emails.. i tryied different methods it does not work..
PS: The server is responding, it says that it cant connect but the smtp server is on.. al ports are open… i have full access to the server.. i can edit all the settings.. thanks…

The plugin’s Test Message Send says:

Test Message Sent
The result was:
bool(false)
