• 10 GOOD reasons to choose Joomla over WordPress for your next website.

• Adding a new Joomla Super Administrator via phpMyAdmin

  Sometimes the Joomla site owners get a bit paranoic after a time, due to lot of hype about site security. Basically is nothing wrong with, a good site security is based on keeping your accounts secure. But what about when you are hired to do something in a Joomla site and you got ALL access (including FTP and database access) but you discover, that the Joomla account you received is only an Administrator. You can do a lot as an Administrator - but often not enough! Don't tell me, that this never happened to you - unless you are a Joomla rookie. What you can do?

• Can't log in with admin, no error messages

  This error comes back time-to-time, especially after a Joomla site is moved from one server to another. The symptoms are simple - but frightening. You try to login to the administrator interface as usual, with your well known credentials, and the login box is reloading whitouth any kind of error message and withouth letting you in. No errors in browser console, no error in the logs, and no errors even if you turn the error reporting to maximum or the Joomla debug on. You can try even the tricks described elsewhere in this site to change your admin password - that won't help.

  Why? Because the cause(s) - yeah, there can be multiple causes - are different from having bad credentials! Let's see what you can do about!

  ATTENTION: these tricks are qualified as core hacks, so be careful: backup, wear your lucky hat, keep your finger crossed - and take any other security measures before you proceed - you can ruin your site easily with a wrong move.

• Two-factor authentication

  Also known as two step-authentication or two-step verification, two-factor authentication is an additional security option for online accounts to help keep them safe.

• User groups

  By default, across all Joomla versions from Joomla 1.0, through Joomla 1.5, Joomla 1.6 to the Joomla 1.7 the basic structure of default user groups is unchanged. The users are generally sorted in 3 main categories, the unregistered/not logged in users, the registered users with frontend only access and the backend users. The exact naming of these main groups are varying across the different Joomla versions, but the default end level groups are the same. The groups and their core permissions are as follows:

• You cannot access the private section of this site

  You just upgraded your Joomla site to latest Joomla 2.5 or 3.* and your regular, registered users cannot login to the frontend, seeing this error:

  "You cannot access the private section of this site"

• You Do Not Have Access to the Administrator Section of This Site

  It's annoying... your own Joomla site don't let you log in in the backend, and you see the above error message... What's happened?

  Humm, there are couple of things you can do. Contrary of the lots of "smart" blog entries on the subject out there (last search revealed about 2 million hits) in most of the cases, regardless to Joomla version the cause is simple:
