Upload Picture In Slideshow Failed. No Error , Just Sorry Dude In The Back

Hello, I am tring to upload pictures in a slide show.
The process failed without any error message.

Now I have "Sorry Dure " printed in the background and I am unable to erase it.
I don'T want to reload the template and start over.
Could you please help me, how to get rid of the sorry dude message ?

That is from a security measure in the upload code meaning the verification token doesn't match. Try restarting your browser or try another browser to see if it makes a difference.

Hello
I really can'T get that thing to work.
I can't upload picture in the galerie on https://www.belartphoto.com/immobilier/
at The end of the process, sorry dude is printed in the BG and no picture is uploaded.
- No error displayed
- I tried all browser (Internet exploorer, Firefox, hrome)

I create a new template on a working page (mariage)
I erase the page Immobilier and create a new page with the same name and stat over by loading the (mariage) template and change the pictures. it's also failed when upload the pictures.

Is it possible that in the database, someting is wrong with the name Immobilier ?

Thnk you all for your assistance.

How about emailing me the link to your Sytist admin with the username and password so I can check it out. Never heard of that actually happening before, but the message is from a security check.
