Check your host, maybe you dont have permission to write to that folder/ not enough space/ incorrect password... there are many things that may cause this

Thank for your support Vlad L. Unfortunately, when I try to change the filepermission through WS_FTP I get the following error message.

! Chmod failed. It may not be supported on remote site.

you need to log in to your host and change the permission over there, if you can not/don't have permission to upload with x5, that means you can not change permission with x5 either.

let me know if you try to do that inside your host and issue did not solved.

if this post is the correct answer, please mark this answer as correct answer.

The strange thing is that uploading was allways possible until a few weeks ago. Nothing has changed into my computersystem, but it is not possible to upload this website. Any other website I have made with this programm can be uploaded as ever before.

Maybe something has changed in how your host manages mobile acces ? Have you talked to them ?

Hans and Julian are the same? if yes, open a new post and ask incomedia to merge your accounts into one account (make that post private).

did you made the changes inside your host? and what was the result? if has been taking care of by login directly to your host changing chmode of your folder. then please go ahead and mark this post as the correct answer.

No, Julian and I are not the same but we have the same problem. I already tried a lot of things but still no result. I have tried to change chmode but get an error result as answer. 
The strange thing is that I don't have this problem with my other websites. Maybe the only solution is to make this website again en maybe it is working.

were do you go to change chmode? can you upload an image of it?
