Dear JASPAR Team,

I am writing to report a technical issue I encountered while using the JASPAR database today.

I received an "HTTP 500 Internal Server Error" message when I was trying to access the website. Specifically, it happened when I was searching for the "JUN" transcription factor binding profile and scanning for a sequence I interested in.

Could you please look into this issue? I rely on JASPAR for my current research and would appreciate it if the service could be restored soon.

Thank you for your hard work on maintaining this valuable resource.

Best regards

Same here. I have been getting the HTTP 500 Internal Server Error since Dec 5th on both the "Add to cart" and "Scan" functions. Looking forward to a fix.Fig. 1.pngFig. 2.pngFig. 3.png
