In my answer to a question, I included a CircuitLab circuit that can be simulated to demonstrate the principle being discussed.

When I edit the answer and the embedded schematic, everything works normally, including the simulation.

However, when I look at my completed answer and click on the "simulate this circuit" link right below it, I get sent to a generic CircuitLab sign-up page. I cannot find any way to actually run the simulation from there. The only way I can do it is to first go back into the SE answer editor.

So, my question is this: Is the "simulate this circuit" link broken for everyone, or is there something peculiar to my circumstances?

Addendum: As I suspected, it has something to do with the fact that I have a CircuitLab account. After I explicitly logged out of CircuitLab, the "simulate this circuit" from an SE page is now working for me.

This is definitely a bug that needs to be fixed.

  • \$\begingroup\$ I just clicked the "simulate" and was directed to a working copy of the simulator. However, upon occasion, I too have experienced what you are questioning. It seems inconsistent in re-directing, but thankfully not too often. \$\endgroup\$

  • \$\begingroup\$ @MattYoung: Yes, but my understanding is that SE and CL have a relationship in which SE users should not encounter it. I'm wondering whether the fact that I have a CL account has something to do with what I'm seeing. \$\endgroup\$

  • \$\begingroup\$ I just had the same problem, but it seems deleting the cookies for circuitlab helps! \$\endgroup\$
