    Make sure you have selected the Joomla DataBase on the left.
    You can also use filter tables by name box to search for the plugin.

    Hi,

    I have looked through the whole forum but did not find this specific concern back.

    I have installed Joomla! 1.5 RC3 without any problem. I also managed to build my website, no problems so far.

    But now, I have no idea what happened but suddenly I could not log-in at back- and front end anymore. The following error is displayed.

    * JAuthentication::__construct: Could not load authentication libraries.
    * Username and password do not match

    I have uploaded all files again (except the installation files) again however, without positive result.

    Does anyone have an idea how to solve this issue?

    Thank you in advance.

    harish

    I turn on the “User – Joomla!”
    (published=0 to published=1)
    Joomla Version 1.5.15

  13. Ron says:

    I entered the database name but cannot see the table called plugins anywhere. Any ideas in 2.5?

  14. Ron says:

    Do you know where the authentication table is at in Joomla 2.54? I don’t seem to see any table named Plugin…

  15. Ron says:

    Regretfully no,
    that is my whole problem.
    When you go to the code for the plugins it seems to use the newer (salt)ed passwrods and it has a helper, but again no reference to where the table is at…ha

    JAuthentication: :__construct: Could not load authentication libraries.

    This is what I get at the admin login…

    I even tried changing the code of the Joomla Authentication php to be SUCCESS for all instances of login, but it still failed.

    Well thanks to Emil who
    has a classified ad extension, I was able to get back into the admin.

    But, I had to do a search for the exact tables in PHPmyAdmin selecting the main database 1st in Joomla 2.54
    I then had to go into the users table and reset the password hash for some reason…

    If you are attempting this, I suggest you pay close attention to the field (State) being set to 1, versus 0.

    Select your Joomla database, find “_extensions” table.
    go to page 3 or 4.

    find this record and change the bold items to these values:
    extension_id 401
    name plg_authentication_joomla

    enabled 1
    access 1
    protected 1

    state 1

    Also find this record and change the bold items to these values:
    extension_id 432
    name plg_user_joomla

    enabled 1
    access 1
    protected 0

    state 1

    Mysql… Find “Extantions” table.

    In extantions table, go to page 3 or 4, and find there “plg_authentication_joomla” – enaible it from 0 to 1.
