use this command like you write or what

iam use this

cd <PATH-TO-ESPOCRM-DIRECTORY> find . -type d -exec chmod 755 {} + && find . -type f -exec chmod 644 {} +; find data custom -type d -exec chmod 775 {} + && find data custom -type f -exec chmod 664 {} +;
To set the owner and group-owner, execute these commands in the terminal:

cd <PATH-TO-ESPOCRM-DIRECTORY> chown -R <OWNER>:<GROUP-OWNER> .; https://github.com/espocrm/documenta...nfiguration.md
