Remove 403 Forbidden Error Permanently

Hello

Every time I repair my Suite Instance I get some new errors and and getting alert “fail”. Pipeline Charts are also not displaying when I checked console I got an errror as 403 forbidden, after that I changed the file permission to 755 and after that it works, but if I am repairing the instance, again I am getting same error.

Can anyone provide me a permanent solutions for that

Hi there,

What is your PHP/MySQL/server setup? Once we know these, we can recommend permissions to set on your installation.

Thanks,

Will.
