Is there a way to just install and check after?

you don't actually need to use the installer, you can just upload all of your files and build the DB through /dev/build in your browser

How do u mean that, is there a tutorial of that?

But my host says its turned on, but just in a different way it won't get detected cause of it

@LiamC I don’t believe you can do that in SS4. We use sspak (https://github.com/silverstripe/sspak) for managing assets in SS4 (edited)

If you upload images via FTP how do you make them show in "Files" ? Is there a way to sync? I know they used to be on SS3?

the installer is just checking the requirements for you, so if it says you don't have the necessary support for it then it's basically telling you that your site won't work if you do install it

Cause my host says the mod_rewrite is a dynamic module, not static. Thats why there is an error

Is there a way to install silverstripe with an error in install.php?

but in asset admin, the translated value is set
