Hi!

I am unable to open the forum at https://aducate.no/lukkatech/forum/

The forum is active according to my page at invision.

Any suggestions on how I can figure out what is wrong?

best regards 

Asbjørn

A blank white page like that typically indicates a PHP error with the server configured to not display the actual error message. You or your host will need to check the server error log to see what is being logged.
