# FAQ

**Q: Can't import the SQL File.**

A: Make sure you are on the latest SQL version.

**Q: Server console: Attempted to concentrate a nil value.**

A: Reinstall the resource, you most likely incorrectly configured the `config.lua`

**Q: I got an infinite loading screen.**

A: This can be because:

* You are using a new PHP version. As of right now the in-game cad only works on PHP 7.2, so please use this version.
* Your URL/Secret key may be incorrect.
* Your hosting provider may be stripping the headers, if so follow this guide: [\[OPTIONAL\] Apache Headers](/hamz-cad-in-game/optional-apache-headers.md)
* If all of the above options are correct and working, then please make a ticket and we'll look into it.
