Hi!

After installing Cachet I navigated to "Manage Theme" in Dasboard to upload a custom banner image.
I accidentally uploaded a wrong image and was about to replace it just to get an error "The banner image field contains a file path that is not permitted."

I tried multiple different images but then I noticed that the site shows the image but the "Manage Theme" page did not. I couldn't even remove the uploaded image. Without making any changes but hitting the save button gave also "The banner image field contains a file path that is not permitted."

After a lot of investigating I figured out the reason. The Filament is rejecting the stored path during validation.
I tried to run "artisan optimize:clear". My .env has "FILESYSTEM_DISK=local" setting.

I had to make an change to:
vendor/cachethq/core/src/Filament/Pages/Settings/ManageTheme.php

I changed:
->preventFilePathTampering()
to
->preventFilePathTampering( allowFilePathUsing: fn (string $file): bool => \Illuminate\Support\Facades\Storage::disk( (string) config('cachet.uploads.disk') )->exists($file) )

After this the "Manage Theme" started showing the current banner image. I was able to delete that and upload a new image
