Error Invalid Login Joomla Update
can't log into the Joomla backend as administrator I can't log into the Joomla backend as administrator There are few common issues that could be causing the problem. The solutions below may help you regain access to your Joomla administrative backend. The first thing that you should try, if you can’t log in to the administrative area of your website (http://domain.com/administrator), is to try to reset your Joomla admin password. If you are receiving the following error message when you enter your login details: JAuthentication::__construct: Could not load authentication libraries. Username and password do not match Most probably the problem is caused by disabled Authentication – Joomla plugin. You can easily fix this problem. First access your cPanel -> phpMyAdmin and select your database from the left menu. If you don’t know exactly which database is used by your Joomla, check this article on the matter: How to find which database is used by Joomla After that you should see all tables of your database, listed on the left side. Select the jos_plugins table (the table prefix – jos_ may be different, depending on your Joomla setup). Find the record named Authentication – Joomla and press the pencil icon (the edit button) for that entry. You should see all preferences for this
Joomla website. He told us that everytime he tries to login, he gets redirected back to the login page with no error! Since he was

a technical person, he told us that he did a research on the facebook login joomla subject and the thinks that it's the session.savepath Joomla problem. This made sense because Joomla uses the built-in PHP $_SESSION joomla login url superglobal variable to maintain information about the logged in person and if it can't save that information to the session, then it won't be able to login the person. So, the first https://www.siteground.com/kb/i_cant_log_into_the_joomla_backend_as_administrator/ thing we tried to do was to check whether sessions were actually working on the site, and they were (we set a session variable in one page and we retrieved in another page) - so that takes care of our client's theory of why the problem is happening. Our second attempt was to check the ACL (Access Control List) of the website as this http://www.itoctopus.com/login-to-joomla-administrator-not-working-and-no-error-is-displayed problem is often associated with incorrect ACL. So we logged in to phpMyAdmin, we selected the database of his Joomla website, and we checked it and it was all clean: the tables jos_users, jos_usergroups, jos_user_usergroup_map, and jos_viewlevels were all OK. We then checked the specific entries in the table jos_assets that might affect the login process, and all these entries were fine. We then tried to do things a bit differently, since our customer was a technical person, he made a backup for the website (the backup consisted of the filesystem and the database) before the problem happened and immediately after the problem happened. So, what we did was that we extracted the database from both backups and started comparing the database of the working website with that of the non-working website. There were about 20 differences - all of them were trivial, with the exception of a very small difference in one of the INSERT lines (the difference is in red): INSERT line in the working version: INSERT INTO `jos25_extensions` (`extension_id`, `name`, `type`, `element`, `folder`, `client_id`, `enabled`, `access`, `protected`, `manifest_cache`, `params`, `custom_data`, `system_data`, `checked_out`, `checked_out_time`, `ordering`, `state`) VALUES

our clients from one server (Network Solutions) to another. The move went smoothly and according to plan and the website functioned after the necessary modifications http://www.itoctopus.com/500-an-error-has-occurred-message-when-trying-to-login-to-joomlas-backend on the configuration.php file. However, when we tried to login to Joomla's backend. We were greeted with the following error: 500 - An Error Has Occurred. Needless to say, the error was not helpful at all. We knew there was an error, but we didn't know what it was. So we started our quest to find the root of the problem in error log order to fix it. We first searched for the string "An error has occurred." in a default Joomla installation - we knew that it was a constant in a language file, and it was! This error was declared in the language/en-GB/en-GB.ini file as the JERROR_AN_ERROR_HAS_OCCURRED constant. Our next task was to search for this constant in the Joomla installation (e.g. the files that joomla login error include this constant), and we discovered that it was included on line 28 in the error.php file located in the administrator/bluestork/system (please note that bluestork can be hathor or system, depending on the template you are using for your backend) directory. Here's the line containing the constant:
error->getCode() ?> -
So we added a print_r($this->error); just before the echo command in the line above, so it became something like this:
error); echo $this->error->getCode() ?> -
Printing the error revealed to us that the error was being generated by the line 153 in the application.php located under the administrator/includes/ directory. Here's the line:
$contents = JComponentHelper::renderComponent($component);
Obviously, the Joomla application had a problem rendering the component, so we checked the renderComponent function located in the helper.php file (which can be found in the libraries/joomla/application/component directory) and we noticed that it wasn't able to execute the login.php file located under administrator/components/com_login directory since the function executeComponent was returning an error. So we debugged the login.php file (yes, we know, this is becoming very tedious
