Hey Everyone,

This is my first website with Kirby, excited for it to be on air  
unfortunately after I uploaded the website to the host, whenever I try to upload content from the panel I get this error:

TypeError  
Kirby\Toolkit\Str::esc(): Argument #1 ($string) must be of type string, null given, called in /home/u379737048/domains/daleelal-khrijeen.com/public\_html/kirby/config/methods.php on line 344

Any ideas why?

You can check your php version using

```auto
<?php
phpinfo();

```

Well, I would need the exact version, there have been quite a few releases between Kirby 3.0.0 and the current latest 3.8.3…

The issue happens because your field on which you call `esc` in line 24 in projects.php snippet seems to be empty.

This is something that has been fixed in later versions of Kirby.

So there are two options:

1. Make sure that the field contains a value or check that in your code before you call `esc` or
2. Update Kirby
