Getting the error “Could not save the model: admin has made changes to this model” in the image below; sometimes, we can open the processes in different tabs and forget. When the change we made in another tab is tried to be made again from the modeler screen in a separate tab, an error is received.
The ideal solution is to close the page where this error was received and continue from the tab where we made the last change. Otherwise, our work will be in vain as the overwriting of other model selections we will drive from here will discard the previous shift. When proceeding with Save, a second duplicated version is created without making changes to the last copy. However, there will be a problem, such as the manual merging of the two versions.
