today we got a strange issue without touching anything, when i try to open our TM1 Web the page is just white, but the Tab is showing the right Title and the Favicon.

it happen to all our users, we tried Chrome, Edge and IE (no other are installed).

the network console says following:

http://hostname:port/tm1web/dwr/en/engine.js net::ERR_ABORTED 404 (Not Found)

We use SSO in our Company with Cognos Analytics 11.xxx architect and Analytics working normal, also perspective and things like the pmhub are reachable.

i also restarted the whole Planning Analytics Service (Admin host, etc) but still just the white page.

I would be very thankful for any idea you have.

Thanks and KR



may i can ask you to check your server it there is a file called "engine.js" in the Webcontents folder. I dont have the possibility to check it here in a fresh installed server.. (We just have this enviroment, no seperated developing -.-")



found a solution, i deleted the whole tm1web folder and reinstalled tm1 at the server, made the config again and it works.

thanks for your help!


Did you recreate the tm1web folder after reinstalling tm1?


i deleted the whole tm1web folder, made a backup from the config file.

Then i installed tm1 as Repair new and changed the tm1web config.
