My Arduino Uno doesn't work with IDE v1.8.4 or Web Editor.

Hi.
I was working a lot of time with Arduino Uno + IDE v 1.0.2 without problems.
Then I tried to use Web Editor but I did not get it to work. The code is compiled but not loaded into the Arduino. The error that indicates is as if it could not record in the memory of the Arduino.
I then tested on another computer with IDE 1.8.4 and the problem was the same.
The USB connection works because I can interrogate the Arduino about its serial number and version.
The programmer I am using is AVRISP mkII
What can cause the problem?
Thank you so much.

It may be that you have the wrong programmer selected in the desktop IDE.
Are you actually using a seperate programmer or just selecting it ?

For CREATE you might want to set up a seperate issue in the correct section of the forum.
There are some quite subtle differences in CREATE installation that if not followed properly will not allow upload.

You might also want to post any error messages but PLEASE use the code tags ( </> )

***Could somebody tell me what is wrong? The same sketch works ok in IDE v 1.0.2
***Thank you very much. If somebody can reply in Spanish I will apppreciate it.
***I add information about the Arduino Board
BN: Arduino/Genuino Uno
VID: 2341

That is such a very very old IDE.

I am sure the issue is not just the IDE but something else.
Also noticed your native language is not english so just going to mention that there are other language options available including Spanish if you scroll down the forum sections.

Please also use coder tags as suggested ( </> ) for code and error messages.
