Internal server error

[elit]

Hi admins, I am having problem with web showing me an "internal server error" banner, addblock/vpn disabled on my latest Opera:

I was also not able to create new thread when I tried few days ago(on WII forum) although it seems to be working here. Also did not work on Firefox btw. And I have these privileges:

You may post new threads
You may post replies
You may post attachments
You may edit your posts

Additionally I would like to ask for new forum under Nintendo for Switch, as I made new tool for un(packing) nsp files, or tell me where to post it(as mentioned I tried WII forum before and it did not work, after submit it just returned and no new thread was created and I also tried PC forums).
