When choosing all logs except alarm log all other will go to system info page.

you mean, Meteohub jumps to the "system information" page when you select "meteohub log" (for example) on the "log files" page?

If so, I bet that your log files have html text in them, that make your browser jump.

What Meteohub version?

2.7b. Also dashboard not working correctly.
