Did you missed the Guest access level in Joomla 1.7?
After struggling for years to set up menu items shown only for guest visitors in various Joomla/Mambo versions prior Joomla 1.7, was a real relief to have an easy and foolproof way to do it. No hacks needed, no scripts to add, no configuration trickery... you simply selected from the Access Level dialog the Guest access group for anything qualifying for this settings (modules for example, but not only..) and you where set! And if you upgraded your site from Joomla 1.7 to Joomla 2.5 the feature where still there. Recently I had a big surprise, I needed the feature in a brand new Joomla 2.5 site... and don't found it!!
Duplicate Template Fix for Joomla 2.5
Since the release of Joomla 2.5 there has been a particularly annoying “duplicate template” bug that becomes clearly evident when you install or update a template. This has caused a great deal of confusion and consternation among Joomla users, but nobody offered an easy to use fix until recently. As anyone else in this business I hit the wall with this bug, until I found a cure for it on RocketTheme's blog.
Error: Invalid login during Joomla upgrade
Today I had to upgrade an old, Joomla 2.5.7 site to latest Joomla, everything went out fine until I had to do the first critical step - the upgrade from Joomla 2.5.28 to Joomla 3.51. Did I mentioned that server has PHP 5.6.25 withouth possibility to upgrade - at least not on short term?
OK, so, wasn't the best setup condition available, but usually this is not a dealbreaker.
And BUMM, I have seen an old "friend", a popup saying:
ERROR: Invalid login
File and folder permissions
This is a key security issue, but unfortunately many of the Joomla site-owners need guidance on this.
First, let's see what you should know:
Joomla is a typical LAMP (Linux/Apache/MySQL/PHP) application, even if runs on many other platforms too. The entire access rights "philosophy" is relying on the native environment's settings.
How to Add Meta Tag Robots in Joomla 2.5 withouth extra tools
By default Joomla 2.5 does not add the robots meta tag in the header and you have no handy tool by default to do it in one place, unless you don't use some add-on which let you do this easily.
But what if you prefer to do it yourself, bare-handed, without seeing even some code? You might be surprised, but in fact in Joomla 2.5 it's very easy to set up meta tag robots for your home page and content articles.
How To Create A RSS Feed For Joomla 1.7+
After I upgraded this site to Joomla 1.7 I wondering, how I can create a RSS feed with all entries to re-create the original functionality we had in the initial site. The problem is that Joomla 1.7 use for this purpose the "Syndication Feeds" module, which picks up the Featured Articles menu item (if any) to create a RSS feed from the currently displayed page.... This works fine - relatively - if you use the default Joomla setup, the Featured Articles menu item being your default homepage. But this isn't my case - and this isn't anymore the case of most of the sites... so I needed to find out something else.
How to detect Joomla version withouth having access to admin?
Sometimes you need to find out the exact Joomla version for a website you don't own for a decent reason - like you are a freelancer and need to provide an estimation for a job on the respective site.
Sure, you can ask the owner ;) but that's the easy scenario.
Fortunately there are relatively easy - and legitimate - ways to find it out, unless the owner of the site hasn't blocked the access to this information. In my personal experience (believe me, I have some) this is rarely happening.

Patch your outdated Joomla installs
As I write this, both Joomla 1.5 and 2.5 have reached their EOL (End Of Life) for long time, and are not developed or supported anymore. This is a huge security risk, so the best advice here is to upgrade your Joomla site to the latest version. But what if you don't have the time/funds to do it right now?
