Your software
My Mautic version is: 5.2.8
My PHP version is: 8.1
My Database type and version is: Mariadb 10.5
My mautic is installed in subDirectory, everything is working except Grapejs.
Your problem
My problem is: Error 404 on Grapejs when opening generator.
404 on : https://mydomain.fr/s/grapesjsbuilder/media?page=1
The site_url in config is : https://mydomain.fr/marketing
i got the same error on everything related to grapejs.
These errors are showing in the log: The errors are display in the Console of my browser
Steps I have tried to fix the problem:
refreshing the app cache
Forcing the subdirectory in grapejs config
I’ve temporary solved the problem by forcing the subdirectory in my proxy, but if you know why Grapejs is not taking sur subdirectory.
