Reasently I updated to nim version 2.0.0 but all my jester code is not working and is providing the error "Illegal Storage use". It is also showing the error while only creating a "Hello World" page.

httpbeast
This is properbly due to httpbeast dom96/httpbeast#80 / nim-lang/Nim#21422. This should be fixed with PR dom96/httpbeast#89 which besides the startup-proc also implemented an addExitProc() for the threads.

You can test whether this solution works by cloning the httpbeast repo by manually installing it:

git clone git@github.com:dom96/httpbeast.git
cd httpbeast
nimble install

For jester to use this new PR it requires @dom96 to release a new tag in the httpbeast repo, before jester will use this version of httpbeast.

Temporary solution
You can compile with nim c -d:dev -d:useStdLib -r server.nim where -d:useStdLib forces jester to use the standard lib instead of httpbeast.
