[nilmerg]

Hi,

first please make sure that the core modules (doc, monitoring, setup, translation) are at the same version as Icinga Web 2. They all show up as v2.8.2 still.

If that doesn't solve the issue already, another module might be the reason. Since the main suspects businessprocess and vspheredb are both up to date, it's one of the others.

The best way to track this down, is to disable each module one-by-one and load /icingaweb2/css/icinga.css in the browser after each. Once this doesn’t error anymore, you’ve found the erroneous module.

Though I've looked at all the modules you have enabled and none of them is the obvious suspect. So I guess it's one of the core modules.

[bgoerner]

Hi,

thanks for the answer.

The older versions come because I downgraded versions.

I updated again:

Sorry I thought this isn't necessary: Please make always a hard refresh (Ctrl+F5/R on windows/linux) of /icingaweb2/css/icinga.css.

[bgoerner]

same result...

[nilmerg]

Arg, then if you don't mind, please apply a small patch which then causes the error to be logged with an excerpt of the position where the error occurs. This hopefully gives a lead where to search further.

Apply patch 4510.txt with cat 4510.txt | patch -Np2 at /usr/share/php/. Then reload and take a look at the log.

[bgoerner]

after patch the page is blank... :(

[nilmerg]

Yeah, but the log should include the error now + the mentioned excerpt :wink:

Sorry, not the access log, Icinga Web 2's own log. That's either /var/log/icingaweb2/icingaweb2.log or syslog or the php error log, depending on your config.

[nilmerg]

That's a different error. The error is Base table or view not found: 1146 Table 'ICINGA_icingaweb.icingaweb_rememberme' doesn't exist. (2.9 requires a db schema upgrade) What we're looking for here is still Expected ')' got '!' in anonymous-file-0.less and the very next message following it.

[bgoerner]

I can't find anything about that... :(

[nilmerg]

Oh well, fine, then apply this patch, the same way: 4510.txt (Will only apply with the previous patch pre-applied)

[nilmerg]

Then /icingaweb2/css/icinga.css shows the details again.

Ehrm, how did you install Icinga Web 2?

I found the piece of code, but not in the current version of Icinga Web 2. Only in an archived packaging repo are these lines, identical to those you have.

[bgoerner]

[root@server php]# yum info icingaweb2 Installierte Pakete Name : icingaweb2 Architektur : noarch Version : 2.9.3 Ausgabe : 1.el7.icinga Größe : 11 M Quelle : installed Aus Quelle : icinga-stable-release Zusammenfassung: Icinga Web 2 URL : https://icinga.com Lizenz : GPLv2+ and MIT and BSD Beschreibung: Icinga Web 2

[nilmerg]

Our packages only install the latest versions of files. These usually override old files, but I suspect this didn't happen at some point on your system.

Check /usr/share/icingaweb2/public/css/icinga/ if there's only a single base.less, or is there maybe a backup file (e.g. base.original.less) of sorts? If there's one, remove the existing base.less and put the backup file in its place.

If there's none, replace base.less with this: https://github.com/Icinga/icingaweb2/blob/support/2.9/public/css/icinga/base.less

[bgoerner]

after replace, error:

Fatal error: Uncaught Less_Exception_Chunk: ParseError: missing opening { in anonymous-file-0.less on line 10073, column 1 10071| // Fix that empty columns don't consume their width 10072| min-height: 1px; 10073| } 10074| 10075| .controls { 10076| [class^="col-"], in /usr/share/icingaweb2/library/vendor/lessphp/lib/Less/Parser.php:631 Stack trace: #0 /usr/share/icingaweb2/library/vendor/lessphp/lib/Less/Parser.php(578): Less_Parser->GetRules(NULL) #1 /usr/share/icingaweb2/library/vendor/lessphp/lib/Less/Parser.php(420): Less_Parser->_parse() #2 /usr/share/icingaweb2/library/vendor/lessphp/lessc.inc.php(129): Less_Parser->parse('\n\n@font-face {\n...') #3 /usr/share/php/Icinga/Web/LessCompiler.php(272): lessc->compile('\n\n@font-face {\n...') #4 /usr/share/php/Icinga/Web/StyleSheet.php(226): Icinga\Web\LessCompiler->render() #5 /usr/share/php/Icinga/Web/StyleSheet.php(264): Icinga\Web\StyleSheet->render(false) #6 /usr/share/php/Icinga/Application/webrouter.php(59): Icinga\Web\StyleSheet::send() #7 /usr/share/icingaweb2/public/index.php(4): require_once('/usr/share/php/...') #8 {main} thrown in /usr/share/icingaweb2/library/vendor/lessphp/lib/Less/Parser.php on line 631

[nilmerg]

Then it's not only this file. Uninstall Icinga Web 2 completely and perform a fresh re-install instead. If that doesn't help, I'm out of ideas.

[bgoerner]

same error after fresh reinstall. :-(

[nilmerg]

Okay, then this ends here I guess. This is most surely an issue on your system, I just don't know where to let you look further. Please ask on the forums for help, include there what you've done already.

Things to note:

• This is an issue with syntax errors in CSS/LESS files of either Icinga Web 2 (/usr/share/icingaweb2/public/css) or some module (<module-install-path>/public/css)
• To nail the location down, use the patches I've provided here and load /icingaweb2/css/icinga.css, but I think that's not necessary as you're only using official modules and I don't know of any issues with any of them (provided the latest version is used)
• Maybe perform a fresh install on a clean Centos 7 VM/container to see where differences are
• Perform another fresh install of Icinga Web 2 and all modules and ensure that all files are gone after uninstalling before re-installing

Hello, I have the same problem after an update just today, here is my situation:

I'm on debian 10.10, I had the same visual result as you (a CSS load problem icinga.min.css as text/html returned instead of text/css).

To solve my update issue, I used the icingacli command to disable businessprocess AND ipl (which was 0.5.0).

then I did apt update then apt upgrade, and tha's it!

Best regards

Hi there,

unfortunately that is not the solution in my case. :(

@bgoerner , thanks! after updating businessprocess it works fine again!

[amyers1616]

I'm on CentOS 7.9 and having the same issue. I tried disabling the two modules but that didn't work for me either. [Edit] - disabling vspheredb made it work for me.

[yoshi314]

In my case it was /usr/share/icingaweb2/public/css/themes/Dark.less and Dark2.less

Could be i had them installed years ago. Deleting the files fixed my problems.

[sim0nium]

In my case it was /usr/share/icingaweb2/public/css/themes/Dark.less and Dark2.less

Could be i had them installed years ago. Deleting the files fixed my problems.

Thanks for this hint! I've had this problem for months now and couldn't find a solution... In the end it was the old and obsolete 'Dark.less' theme!

After deleting this theme-file in '/usr/share/icingaweb2/public/css/themes/' the login page is displayed correctly!
