rtrepp

First tried wordpress own gallery system.
When i upload its says error and show that he cant upload picture. Then when i go media link, it shows there is picture but i cant use it.
Then i downloaded some plugin dont remember what was the name there was over 60k+ downloads for that plugin.
But this aint working too.

And this warning text is on every page where i go.

And there is now two linked pictures what i uploaded to server, but this isnt right.
