Hi all,

I have big problem which I have noticed after last Umbraco update, but it could be something else, I am not sure that upgrade is the reason.

I have code where I can upload and delete images in Media section from the fronted of my website.

I have few fields where I can upload images. For example if I try to upload 1st image its okay, than if I upload one more image, again its all good, after that If I delete 1 od this images programatically it works good and than sometimes, not always which is so wierd i get this error:

Umbraco.Core.Exceptions.PanicException: 'failed to get last child with id=-1'

In this line: IMedia uploadFile = Services.MediaService.CreateMediaWithIdentity(model.File.FileName, mediaFolderId, "Image");

This is my code for image upload to media section:

IMedia uploadFile = Services.MediaService.CreateMediaWithIdentity(model.File.FileName, mediaFolderId, "Image");
                uploadFile.SetValue(Services.ContentTypeBaseServices, "umbracoFile", model.File.FileName, model.File.InputStream);
                Services.MediaService.Save(uploadFile);

If i continue after that error and than try to delete some other Image i get this error:

Umbraco.Core.Exceptions.PanicException: 'failed to get next sibling with id=3709'

On this line:

Services.MediaService.Delete(item);

Please somebody help me with this, i can provide more informations if needed for better understunding.

BR
