Your software

My Database type and version is: 10.3.36-MariaDB-cll-lve - MariaDB Server

Your problem
My problem is:
my screen freezes if i add smtp details in configurations. even if i refresh the new smtp is not updated. please help to fix this

These errors are showing in the log:

Steps I have tried to fix the problem:

This might be a file permission issue.

Log into the sever via terminal / putty / SSH

Run

sudo chown -R www-data:www-data /var/www/html/mautic/

Then

sudo chmod -R 755 /var/www/html/mautic/

If your path to mautic is different update it. For example

sudo chown -R www-data:www-data /var/www/mautic/

And

sudo chmod -R 755 /var/www/mautic/

Are there any special characters in your password? You can add your SMTP password directly from the Mautic configuration file from your server’s file system.

Hello,
There is no special characters
