    just few minutes before, i logged into forum admin panel from my mobile,
    everything was working fine, then just before i tried logging into forum admin panel in my PC,
    i got this error, now everywhere i am receiving the same :(
    just want to mention that, i migrated my forum to VPS last week,

    this never happened before,

    I already browsed through forum,
    somebody suggested truncating the session table
    will it work in this case?
    can i do this via phpmyadmin??

    This is the error, -

    Fatal error: Class 'XenForo_ViewAdmin_Base' not found in /home/rbharathi820/public_html/forum/library/XenForo/ViewAdmin/Login/Form.php on line 4

    That would suggest a file is missing.

    Try uploading that file again: library/XenForo/ViewAdmin/Login/Form.php

    This might be an indication that the server move had some issues; you may encounter other issues if any other files weren't copied across.

    Try uploading library/XenForo/ViewAdmin/Base.php, that seems to be the missing file.

    Hi Brogan,
    Thank you for quick response,
    forum was working fine for last 10 days after migration.
    today only i am facing this error,
    anyway i tried re uploading that file,
    but the problem is still there!!

    Have you been able to log in to the ACP for the past 10 days, since migrating?

    If so, you should contact your host as errors of that nature (i.e with the file system) don't occur spontaneously.

    :eek: kind of small thing, i didnt tried all this re upload because,
    forum was working fine in these days,
    i didnt change anything with ftp manager,

    so i thought it related with some thing other.
    Thanks Jeremy :) :)
    now its working.
    i wonder , what happened to that file before anyway thats not needed,

    Yes Brogan, i did everything on admin panel, for the past ten days.
    i think something happening with server side, so, will speak about this, Thanks a lot for your quick support.
    Being happy XF customer.
