I'm upgrading my osticket set ups from 1.17 to 1.7.5 right now. On the first one, I switched out the osticket wwwroot files (it's IIS, not apache), started the site again in IIS, deleted the setup folder. But then has a message, "Please change permission of config file (ost-config.php) to remove write access, e.g. chmod 644 ost-config.php." I've heard of this.... I'm not 100% sure what to do though. Right security tab and remove write permissions?
It's osticket 1.17.5 now
IIS 10
Mysql 8.0.31
PHP 8.0.24
so Windows.
