TM1 Web White Blank Page

Post by HighKeys » Wed Feb 12, 2020 2:09 pm

Hello,

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.

If i monitor the network it says a file called "engine.jsp"" is missing. I can't find that file in the webcontents folder, is this normal?

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

Does it do this for you or all users?
Have you tried holding shift and clicking the refresh icon in your browser? (sometimes Ctrl+Shift+Click Refresh)

Does the login page come up where you can select which server to connect to or not even that? We had something similar recently: no login page, just white screen. In our case, it was only Chrome that was causing the issue and the affected users could still access TM1Web in IE. Clearing the browser cache in Chrome fixed the issue.

Hi gtonkin,

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

the network console says following:

Code: Select all

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

I tried your tip but it didnt work for me/us.

@ascheevel We dont see the login page just white blank in the source its a div called something like "Tm1 Web backgound"

Clearing cookies and cache also dont brings tm1 web back


Thanks for your help

I'm very sorry to ask here, but does anyone have the possibility to check the webcontents folder at a enviroment where TM1 Web ist running?

Would be very interessting if you have the folder "dwr/en" and the file "engine.js"


thanks!

Hello,

FYI i unpacked the tm1web.war file and copy it again to my webapps folder to make sure nothing there is missing, and checked the configs again, but still just the white blank page.

Thank you!

So i can say nobody changed the TM1 Folder files, i also extracted the "tm1web.war" again to be sure that i have all files that i need.

If you check your network monitoring in your browser, do you have any errors listed there?

Thanks for your help!

Hello friends,

i found a solution, i deleted the whole TM1Web folder and installed TM1 again on the server, now it works.


I have a additional Question, before i had this issue, we dont see the mask to select a server in tm1web, now i can switch between our dev and prod enviroment, is there a way to change it?


thanks for your help!

Hi,
the TM1web config is your friend for that.

In ..PATH_TO_YOUR_INSTALL\webapps\tm1web\WEB-INF\configuration\tm1web_config.xml
<add key="TM1ServerName" value="YOUR_DB_NAME_HERE" />

You should also set the Adminhost, than your users do not see this input field
<add key="AdminHostName" value="" />


best regards
orlando
