**Your software** My Mautic version is: 5.0.3 My PHP version is: 8.1.27 My Database type and version is: mysql Ver 15.1 Distrib 10.3.39-MariaDB, for debian-linux-gnu (x86\_64) using readline 5.2 **Your problem** My problem is: I upgraded mautic from 4.4.10 to 5.0.3 after that new feature is showing EMAIL DSN. I tried install `composer require symfony/sendgrid-mailer` but not sure where it is getting installed. Please guide the correct path to install this sendgrid-mailer. These errors are showing in the log: Unable to send emails via “sendgrid” as the bridge is not installed; try running “composer require symfony/sendgrid-mailer”. ---

You’ll need to clear your cache after requiring a transport. You can do this using the [Command Line Interface](https://docs.mautic.org/en/5.x/configuration/command_line_interface.html): `mautic:cache:clear` There were a couple times this didn’t work and we had to manually clear cache. ---

Having the same issue, having done this on my A2hosting cpanel - Terminal, I received this error: `bash:bin/console: Permision denied` ---

Sounds like a permission issue `chmod a+x [path/to/mautic/]bin/console` Or, invoke it using PHP `php [path/to/mautic/]bin/console mautic:cache:clear` ---

@marcus42 thanks for the speedy reply! (brave newbie here) I gave that a roll, and I think it worked. I got no response from Terminal other then a fresh prompt line. Went back into Email settings and received the same error. Perhaps you can help me trouble shoot this too! My Mautic version: v5.0.4 My PHP Version: 8.1.27 EMAIL SETTINGS: ![Screenshot 2024-04-16 180553](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/3/3d9ac4f79f0823c0065ba59fcd4f5efbd0e42aa8.png) .env File: ![env](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/2/230e807ff6e87dc8ecf2a349a77ba6b8b9d897c5.png) ---

No output == success most likely. Regarding your second issue; I would get rid of the “sengrid+” in the “sendgrid+smtp” and give it a try. ---

Hi @marcus42 , Thanks for continuing with me here… when I try that I get this error: ![Screenshot 2024-04-22 125519](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/a/a8255a05b3bc9147ff9022e9ab7e23713c806598.png)
