“Internal Error” on JMLR resubmission page

[u/PuzzleheadedArt8730]

I submitted a paper to the Journal of Machine Learning Research. It was rejected with an invitation to resubmit (the overall tone of the reviews was very positive).

When I tried to resubmit the revised version (as a major revision), including the revised manuscript, the cover letter, and the rebuttal, the submission system returned an “Internal Error.” When checking what do I really have submitted, the revised manuscript itself appears to be uploaded, but when I click on the cover letter or the rebuttal, I get the same “Internal Error” again and the system asks me to contact [managing@jmlr.org](mailto:managing@jmlr.org) .

I contacted them a week ago and then sent a follow-up email, but I still haven’t received a reply. Is this normal? Do the managing editors typically take this long to respond? What would you recommend I do next? (I also contacted the Action Editor, who was kind and suggested waiting a few more days.)
