My system

  • Almalinux 9
  • Apache 2.4.62
  • PHP 8.2.27
  • Mysql 8.0.41
  • packege Mautic 5.2.3

My installation step

Step 1
I open the website where Mautic is hosted.
The environment check is perfect, and the SSL configuration is correctly present.
I click on ‘Next Step’.

Step 2
I configure the database access parameters.
I click on ‘Next Step’.
The tables are successfully created in MySQL.

Step 3
I configure the administrator’s username, password, first name, last name, and email.
I click on ‘Next Step’.

I get the following error:
“Uh oh! I think I broke it. If I do it again, please report me to the system administrator!
‘500 Internal Server Error’”

This log file is empty:

  • /var/log/httpd/error_log
  • /var/log/php-fpm/error.log

Can you help me?

I fixed it.

By enabling Mautic’s debug mode, I saw that the issue was with Doctrine.

I shared the error (retrieved from Mautic’s log files) with ChatGPT, and it provided me with the sequence of commands to fix it.
