Hello. Is there any way to install extensions to the appImage version? I get "bad gateway" when I try to do that.
Linux Mint 21.3

I don't think it is related with appimage.
I use tar.gz version, I get Bad GateWay error too.
I renamed my extensions folder to reset SMath
I couldn't download plugins again.

I tried same steps with a Windows laptop. It could download plugins with no problem.
Issue is either Linux, Mono or smath server is rejecting either of them.

Hello.

Issue is fixed now. So one can try to install plug-ins on Linux and expect the success.

Best regards, Andrey Ivashov.
