Add-on validation fails with error 403

[kir]

Describe the problem and steps to reproduce it:

Cannot upload new add-on version for https://addons.mozilla.org/en-US/developers/addon/checkvist-bookmarklet/, with error:
Received an empty response from the server; status: 403

The add-on was previously disabled due to usage of eval in the code.
Now, eval is not used. Also, with local validation, there are no errors, only some warnings.

I'm afraid I'm not sure how to escalate the problem further.

Sorry for not getting back to you sooner. I see you managed to upload a few versions since, so I'm going to close this, but let us know if we should re-investigate.
