i can log into whm fine and make accounts, do all that but when i go into list accounts and click on the cpanel icon for a user. it goes to the login screen for the frontend but then after the password is put in it just loads a blank screen.

i have searched the forum (and google) looking for answers but havent found anything. one guy had the same problem last year but there was no solution to his thread.

the permissions for the folders are fine.

I'm running WHM 10.8.0 cPanel 10.9.0-R139 / FreeBSD 6.1-RELEASE i386 - WHM X v3.1.0

any help would be greatly appreciated.

thanks for that dude but yeah that was already unchecked. the cpanel icon was there. its just shows nothing after you login, even without going through the whm

...http://myip:2082

i get the login for cpanelX.

i put in the correct login details and it logs me into an empty screen.

this is from a view source of the page i get

If this is a new server, make sure you choose a theme under
Server Configuration<<Basic cPanel/WHM Setup <<Default cPanel Theme
* Enter the default cPanel theme for newly created accounts whose
package does not specify a theme.

If that fails,

try running from root in ssh

/scripts/portsup

then run

/usr/local/cpanel/bin/checkperlmodules

after that finishes, run

/scripts/upcp --force

see if that clears it up.

What FreeBSD version are you running on your server?

Did you check the log file? /usr/local/cpanel/logs/error_log
Run these two commands at the prompt and see if that helps:
/scripts/portsup
portupgrade compat4x-i386-5.X (Assuming you are running FreeBSD i386 v5.3 or v5.4)

WHM 11.1.0 cPanel 11.1-E8012
REDHAT Enterprise 4 i686 - WHM X v3.1.0

I am having the same problem on one of my cpanel servers.

I upgraded to the latest edge version so I can use the X3 theme, and all of the themes (x, x2, x3) do not work. Instead, I see only a blank screen. This happens all of the accounts on this server. Cpanel now does not work.

I tried these options...

/scripts/portsup
/usr/local/cpanel/bin/checkperlmodules
/scripts/upcp --force

... but the problem remains. I have switched back and forth from the ssl port to the non ssl port and I have unchecked the force redirect to ssl and also checked that option. In all cases, the cpanel remains just a blank page. The login prompt comes up, proper user password is accepted, and blank screen.

Anyone have any suggestions as to why this is happening?

Any errors in the log files: /var/cpanel/logs/*

In addition, login to the WHM >> Tweak Settings >> System section >> un-check the following: Disable login with root or reseller password into the users' cPanel interface. Also disable switch account dropdown in themes with switch account feature
See if that helps.

Contacted Cpanel support and this is what they said....

You'll need to increase RLIMIT_RSS for cPanel to function properly. The
following error is being generated:

The rlimit 'RLIMIT_RSS' is set below the maximum sane threshold for cPanel to
function. Currently it is set at [soft:78643200 hard:78643200]. Please
increase it to at least 134217728.

Since I recently had my IT company upgrade our Kernel to 2.6.9-42.0.10.EL , I had my IT company change the RLIMIT_RSS setting as suggested, and the issue is now resolved.

Check /var/cpanel/cpanel.config

Cehck
engine=cpanel (Not cpanel.pl.)
enginepl=cpanel.pl

That's one of the solutions. Good point. Oe of our clients had the same exact problem few days ago, but none of these solutions worked for him. To fix the problem, we had to rebuild several corrupted files.

When this happened to us it was because the skin being used had somehow become linked to a non-existant one.

Damn fine question. Can anyone answer this?

I'm having this problem sporadically. Restarting cPanel doesn't solve it, only a full system reboot. Which...well...certainly isn't desireable.
