How to reset WordPress permissions?
If you have developed your site locally, or you’re transferring it from another host, there is a good chance that some of your files and folders permissions are not set correctly.
Go to your Site Tools > WordPress > Install & Manage > Manage Installations > kebab menu for the corresponding domain > Reset Permissions.
The tool will take care of the reset setting all your folders permissions to 755 and your files to 644 which are the correct and secure permissions for our hosting platform.
