cannot write in jupyter cell #3028

Open ecamossi opened 7 years ago

ecamossi commented 7 years ago

Hi everyone,

I never had this issue before, but when I add a new cell between existing cells, I cannot write in it. I'm able to copy and paste from an existing cell into the new one, but I may just delete the content and I'm not able to modify it. I tried restarting the kernel, the workstation, but it doesn't solve the problem. It doesn't seem related to the keyboard layout (cf. issue #2379), because mine it's US.

Thanks in advance for any suggestion. Kind regards, -Elena

Any errors in the browser's Javascript console when this is happening? Have you tried with another browser?

ecamossi commented 7 years ago

Hi takluyver,

thanks for the suggestion! Indeed, with IE it doesn't happen!

Whan I got the error, I was using chrome. For the sake of completeness, I open the js console and this is what I saw jupyter-error

There was no error when I was trying to write in the new line, but it seems there were other errors before. I don't know if they are related to the strange behaviour I got.

Regards, -Elena

The first error ('Failed to load resource...') might be related, but there's nothing obvious there. Do you have any extensions installed in Chrome?

Hi Thomas,

Thanks a lot for your suggestion, indeed I have many. So I tried again with Chrome disabling all extensions, and indeed now it works as before.

I copy here the list of extensions that were enabled when I got the issue:

By the way, the failed resource error is still there. It seems related to the notebook, by the way (regarding extension widgetsnbextension or ipywidgets 4.0):

Here the error:

jupyter-error2

OK, sounds like that error is not related, then.

I recall there was some issue with Lastpass on Chrome before, but that may not be at fault this time.

Thanks this worked

It still doesn't work for me. Whenever I type in Jupyter Notbekkok (Through vocareum online environment) I cannot edit any cells. Does anyone know If maybe I just put on or off somekind of setting?

When I type A, I just get another blank cell above. But when I click in a code cell, I cannot alter anything.

Since now I have been facing the same issue with jupyter but after disabling the extensions It is working good now
