Joomla Admin Locked out-JAuthentication
Recently I’ve locket myself out of Joomla Admin as I have accidentally disabled the Authentication – Joomla plug-in – JAuthentication. Joomla Admin was locked out.
When I tried to login to Joomla Backend with my Administrator account I’ve received the following error:
JAuthentication ::__construct: Could not load authentication libraries. Username and password do not match.
To solve this I had to edit the Joomla database table to enable Authentication – Joomla plug-in.
Here’s how to do it:
Login to you CPanel | On the home page scroll down to Databases and open phpMyAdmin
In the left pane of phpMyAdmin select your Joomla Database. From the same pane, select jos_plugins table
Now click on the pencil item to edit Authentication – Joomla row
In the ‘Published‘ row change the value from 0 to 1
Make sure that Save is selected from the dropdown list and click the Go button.
That’s it, you should be able to login to Joomla admin now
NOTE: Once I’ve changed that, I still couldn’t login to Joomla Admin. The reason for this is that I had jos_plugins and bak_plugins tables. Once I changed the value for the bak_plugins table I was able to login.
In my case, duplicate tables exist because I’ve migrated from 1.0 to 1.5.
Comments are welcome.
Very thanks for this great solution. You saved me.
THANK YOU GUYS!!!
I have already problem in 1.5.x

jos_plugins>published row> pencil icon > default value 0 to 1>save>go.

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.

Thanks!!! very good note!
Thank you very, very much!!!!

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.

I sellected the database on the the left, but I cannot find any table named plugins. Any ideas in 2.5 where that would be?

Have you tried with extensions table?
Do you know where the authentication table is at in Joomla 2.54? I don’t seem to see any table named Plugin…
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.
thanks a lot! that helped me out of the disaster ! 😉

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
Thanks,works like a charm, you save my life

Hi Sam, did you do everything as stated in the article?
Cool Ron thanks it helped me and now working fine!
i loooooove you, you reject my life 😆
Thanks for the info, save my time. 😆
Muchísimas gracias amigo me sirvió su información
I can’t find the jos_plugins
Hi Helder,
forget about the prefix, try to find the _plugins table.You are probably using different DB prefix for your Joomla tables.
🙂 Thank you !!!!
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.
Thank you for sharing this useful tips
I received this same error. I logged into my phpmyadmin and its says that I have 0 tables. I try and search for tables and nothing comes up. Any new suggestions?
thanks
Thanks a lot!
