Can't save changes in module builder

After I add field and press save in module builder nothing changes. I even set permission for whole folder 777.

Hi Toko,

What is your environment/server set up and what version of SuiteCRM are you running? We would not advise setting 777 as this is not safe, and there are many areas you need to take into consideration when setting permissions such as the config.php file.

If you can detail your server set up, we can suggest permissions to set.
