Ionic Framework ionic-v3

I have small issue with blank image when I upload my web-app on the host (see the picture)

So why this blank image shown, every thing works fine except this blank image, I searched a lot about it but I couldn’t find the solution

Note: I used this command to generate browser build
"Ionic cordova build browser --release --prod --generateSourceMap false

I think this blank image for my app splash screen but how can I fix it ?

I think I got the solution by delete config file of released files … but still I’m not sure this way is the only solution or there is an other solutions !
