Have you tried pressing the F5 key to update EasyEDA to the latest version? If the PCB is part of an access controlled project, please also see this thread: https://easyeda.com/forum/topic/Saving_a_Schematic-p3XRxrJDj

it's V3.3.5 Works under Safari! (Export as source from Firefox, imported to Safari, save is ok) Klone works under Firefox. It is a bit more complicated: Save as module is working with the file! This created module can be saved normally then!!!!!!

I can save other files under Firefox! Seems to be related to a certain file, not the browser?? Hope I do remember correctly what happened with that file: I was applying changes to this file, quite a lot. Then (before saving it) there was the popup regarding update to new version of Easyeda. I tried to save my work, but this time it was not possible, Easyeda restarted with the new version and all the changes were lost :( This File can not be saved or saved as.... If you need it, you can get it, you should produce it later (with the changes ;)

Ooops, seems I do have a Safari and another Firefox identity somehow :( How can we correct that? Sorry for that!

Sorry Axel, Could you clarify please?

@Ooops: Directly after I replied (with Safari), the latest post appears with as_axelschmidt as author, the previous posts were As_axelschmidt (created with Firefox). So I assumed, that I did register two times, once with firefox, the other with Safari. But after refresh of the browser window everything is OK, author of my last post also appeared as As_axelschmidt. So forget it, sorry for the confusion, I have to go to bed :) Don't work too long!
