Hi all,

Just wondering if anyone is having problems with logging in to cpanel accounts after the update.

It seems that accounts using the theme are throwing errors and users cant log in. I have also tried to access through WHM (list accounts) cPanel and the same error displays.

Code:
A fatal error or timeout occurred while processing this directive.

Template::Exception:
    [TYPE]=[undef]
    [INFO]=[Branding::get_available_applications(HASH(0x661c510)) failed: (XID 4zvafb) The system failed to parse the JSON stream from the file “/usr/local/cpanel/base/frontend/paper_lantern//dynamicui.conf” because of an error: garbage after JSON object, at character offset 40053 (before "file=>lverubysel,ski...") at /usr/local/cpanel/Cpanel/JSON.pm line 119, <$_[...]> line 1.

]
    [TEXT]=[





<script type="text/javascript">]
at cpanel.pl line 1234.
    cpanel::cpanel::cptt_exectag("/usr/local/cpanel/base/frontend/paper_lantern/index.auto.tmpl", 1) called at cpanel.pl line 5214
    cpanel::cpanel::run_standard_mode() called at cpanel.pl line 869
    cpanel::cpanel::script("cpanel::cpanel", "./frontend/paper_lantern/index.html") called at cpanel.pl line 331
Is there a why I can force all accounts to use another theme in the meantime.

You might want to try forcing a cPanel update again to see if that's of any help with this.

x3 has been or is being removed and going back to it out of the question.

If the forced update doesn't work for you, open a ticket directly to cPanel Technical Support about this, they'll get you sorted out.

Just to add, I am not seeing that issue on my end, no. Do you have any special customizations or plugins for cPanel of some sort enabled on your server?

update- Edit package manager > Change package to use the x3 theme.

Manages to log in but no icons are displayed on this.
- Removed -
The buttons "reset all interface settings and reveal all boxes do nothing and the page produces 4 JS errors in console.

Hmmm we have these,

and a newrelic monitoring plugin.

The only thing that I think would add to the template is maybe the softaculous ??

I use softaculous too, no errors with it. Not sure if the OneClick SSL is a cPanel interface plugin or not, same with the newrelic thing, can cPanel users access these two from within their cPanel? If yes, the plugin might need an update. The others you list are not cPanel plugins a cPanel user can access, they're accessed via WHM.

Same result for different browsers unfortunately. I have run the force cpanel update from whm and it appears to get stuck at around 88%. It's been sitting there for over an hour however cpu an memory usage have dropped back to normal and I cant see any update processes being run in the process manager. I have tried to login in again ... same result.

On cpanel login

We have passed this on to our provider T3 support and they are looking at the templates, this may well end up at cPanel support.

Got the same error

Changed theme for the package that the account uses back to x3 and it worked.

Found a number of accounts having the same issue on different servers. Mostly accounts having x3mail. Changing them to x3 solved it.

Hope this helps

edit: A lot of the accounts having packages where it said paper_lantern, actuall y had x3mail still and that did not work.

edit2: Changing all accounts can be done via WHM Home »Multi Account Functions »Modify/Upgrade Multiple Accounts

A Response back from cPanel, sent from my provider. I currently still have no access so I'm just checking to see if it has been implemented.

cPanel have acknowledged that this is a known issue, and they are tracking the bug under ID "CPANEL-3875" which can be tracked via Change Logs - Documentation - cPanel Documentation.

The recommended workaround has been implemented and the Paper Lantern theme now appears to be working correctly.

WORKAROUND DETAILS:
Comment out the below two lines from /usr/local/cpanel/base/frontend/paper_lantern/dynamicui.conf:
#file=>lverubysel,skipobj=>1 # this line is modified by /usr/share/l.v.e-manager/cpanel/utils/dynamicuictl.py
#file=>lvepythonsel,skipobj=>1 # this line is modified by /usr/share/l.v.e-manager/cpanel/utils/dynamicuictl.py

Working Update: I just nano'd the file as the server still had the error. I saw that there were 4 lines at the end of the file the first two had been commented out by my provider but it seems that they had been added again (presumably by the dynamicuictl.py) script. I just commented out the extra two and now it seems to be letting me log in.

I would imagine I would have to go in and add more comments as time passes (if extra lines are added) but for now its something I can work with.
