Images not showing after moving website

Hello all,

I have searched and searched but can't seem to find it.
I build a newer webshop in OC 3.0.3.1 on a seperate domain. shop/testing
I asked my hosting to tranfer it to the right domain (where my webshop always was).
Since they moved it I can not see any productimages and I can not find them (they are there, FileZilla shows them to me) or add new ones.

I added a picture of the warning label I get:
"warning: select a directory!"

If someone knows the solution or the topic where to find the solution please let me know!

Most likely errors in your config files in root and admin folder.

hoogstwaarschijnlijk zijn de config bestanden niet goed aangepast waardoor het pad naar de fotos niet goed staat.
let erop dat je de beide config bestand in de hoofdmap van de site en in de map admin goed aanpast

Hooray!!
It worked! Thank you so much!
