    Without further information we cannot help you. Output of service imscp_panel status?

    If you cannot figure out alone, give us acess to your server.


  • Dear Nuxwin and UncleJ ,

    thanks for your patience, information and Engagement.

    I searched in different logfiles and collected the hopefull needed information for you.

    So here is what i found out:

    Beside this I sent an eMail to Nuxwin for the chance that you would ckeck some things at the server yourself <3

    I thank you a lot!

    Greetings from Bonn, Germany,

  • @Nuxwin worked hard on my Server to find and resolve the problem :thumbup:

    However this could happen there was a bad symlink for the panel PHP binary ;(

    Just about the history of this Server:
    Fresh Installation with Debian Jessie 8 and i-mscp 1.2.17 in 03/2016
    Update to i-mscp 1.3.7 in 11/2017
    Update to i-mscp 1.4.3 yesterday.

    I got the advice from @Nuxwin to update more often :idea:

    I thank you a lot for your hours :thumbsup:
