SMIME Internal Server Error on Certificate Verify



  • When opening a SMIME signed mail (internally sent) I get an error 500 on Apache. That is the log file. Any advice? (Running latest SMIME Plugin and Core build 520)

  • Good morning,

    I am having a similar problem. When I open an encrypted email I get an error and in the log file I can see this:

    Mon Jul 01 14:18:05.950394 2019] [:error] [pid 9089] [client 127.0.0.1:43534] PHP Fatal error: Uncaught Error: Call

    What do I need to do?


  • Kopano

    Could you share information about your setup?
    OS, php version, WebApp version etc



  • @marty

    WebApp:
    3.5.8.2339+1314.1
    Kopano Core:
    8.6.9
    Z-Push:
    2.5.0+0-0

    And the latest version of the S/MIME plugin downloaded from the community site yesterday.

  • @yep_DD
    I am having exactly the same problem



  • Note that I am able to view the email from my mobile phone and also if I forward it.



  • @marty

    I was wondering if you need any further information or log files for this.


  • Kopano

    By the look at the error it seems you’re missing php-bcmath (or it’s not active)



  • @marty

    Marty that fixed my problem! Thanks a lot!!

    Question: should that package be in some dependencies? For example of the S/MIME plugin?

    Otherwise how do people know that they have to install it?


  • Kopano

    @mcostan This should be the case already:

    Ubuntu 16.04 example:

    apt-cache depends kopano-webapp-plugin-smime
    
    kopano-webapp-plugin-smime
      Depends: kopano-webapp
      Depends: php-kopano-smime
     |Depends: <php5-curl>
      Depends: php-curl
        php7.0-curl
      Depends: php-xml
        php7.0-xml
      Depends: php-bcmath
        php7.0-bcmath
      Conflicts: <kopano-webapp-smime>
      Replaces: <kopano-webapp-smime>
        kopano-webapp-plugin-smime
    

    Did you upgrade your OS and php-version recently? I can imagine some issues there, but that’s something for the admin to double check imo.



  • I updated PHP a few months back and then installed the latest SMIME plugin.

    Perhaps it found the old PHP dependency which was installed with the old version of PHP and it thought it was ok…



  • Problem fixed, thanks a lot!
