Accessing the administration panel
Okay, you've installed your Joomla site, and want to began to master it. You click on the administrator link in the frontend and instantly hit the wall: a blank page is showing up. What's the deal? The cause is generally simple: This is happening almost always because your 'live-site' setting in your configuration.php file doesn't correspond with your Administration URL. You either have a www in your live-site setting in your configuration.php file and you are accessing your administration backend without the www or vice versa. It's highly recommended to correct this, the problem can impact even your site's Google rating.

Do you have some old Joomla site (pre Joomla 1.5.6)? then is very likely you will got - or already have - a site running only halfway, full of errors saying
Yeah, you might allready guessed it, the PHP 4.* end of life-cycle is wreaking havoc in Joomla 1.0 sites and some early Joomla 1.5 implementations - or even newer sites, having badly coded third party extensions installed.
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.
Google Indexing '?tmpl=component&type=raw' Webpages
When doing Search Engine Optimization tests you discover that your web pages are duplicated in the Google index. One record is correct and the other includes '?tmpl=component&type=raw' in the url. Usually panik strikes instantly... since the hype about Google's "duplicated content penalty" is still high, giving more, than 1,2 million hits, despite the fact that Google officially denied the existence of a dumb penalty for such a "duplicates", claiming that they are penalizing only copycat pages. so, it's mainly a false alarm... but since all SEO workers are living (and dying) form the confidence - or lack of confidence - of their clients, it's a problem, wich should be solved.
But let's see first, where these links are coming from, then we will find an easy cure for the problem itself.
Help! My editor background is coloured!
Yep, that's something you can experience with any of your new templates, especially the ones with colored/dark background. Why this happening? And more important, how you can fix it?
The answer to the first question is simple: the 'WYSIWYG' editors used in Joomla are just doing what the name implies: are taking the template's CSS file and rendering the newly entered content to be as close to what will be shown on the site as possible. And if your template's background is colored or an image file is used to fill your background, then that will be used there too. The fix is relatively easy in the case of most current editors. Almost all of them have the possibility to use a special CSS file in the editing pages. Here we will show you the recipe that works for the family of editors based on TinyMCE editor, delivered by default with Joomla (as JCE), but the solution is similar or can be easily adapted for all such advanced editors.
How to change / set the Joomla template programmatically from within a Joomla 1.5+ component

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.
How to remove 'Welcome to the Frontpage'
I did not realised until recently how hard may be even for some seasoned Joomla webmasters to get rid of that 'Welcome to the Frontpage' text from their Joomla site. But talking with couple of customers and being even hired for do this made me curious, and I Googled for 'Welcome to the Frontpage'...
The result may be surprise you... my last attempt ended on 25.000.000(no kidding...) hits.
So, there is the free-for-all recipe:
How to remove Joomla copyright info
Joomla is a great piece of software, and the developers are deserved allready full support for keeping it evolving. One of the easy methods are to keep those Powered by Joomla texts and messages in place, and visible. But what if - with good reasons - you want to get rid of those? For example to make less obvious for Joomla-hackers to identify your site as a possible next target - to name only one of possible multiple reasons. (Read also this article about how to remove the Generated by Joomla! tag!) Or you may want to keep it, but a bit tweaked, to reflect better your contribution to that site of yours. The same questions are arising: where that footers are coming from?
How to remove the Joomla generator tag

How to restrict a user to access only one component in admin

I want the print and email icons back as in previous Joomla!
A client called me one of these days with this request. He told me, that what was once a simple one click action to print, email or edit an article in frontend in Joomla 1.5 has became an uncomfortable, two click process, which in some devices proved to be increasingly difficult. After a bit of digging around I found for him an easy to implement template override which make him happy.
Infinite loop detected in JError
Today I have faced a strange, never seen before error. I have worked on recovering a server with couple of old Joomla sites after a major crash, when one of sites ceased to "fly" again, and showed up nothing else but a white screen with this text:

Joomla Chrome and Template Overrides
When you developing a template for a new site you often get stacked, and hit your head against the wall: the code outputted by Joomla sometime severely limits your ability to format the output as you wish. This is true not only for Joomla 1.0.*, but partially for the Joomla 1.5.*. Yes, partially, because you can do things here - and you can do a lot. Searching for a solution for a problem I had run into developing a template for one of my clients I found this great tip of Jonathan on his blog on http://www.beckettwebdesign.com:
Just turned SEF on and inner page images where gone
Did you had this experience? Couple of days ago I just turned on SEF and the inner pages began to act weird - images disappeared, modules misbehaved, scripts weren't loaded...
My first reaction was that I have set something wrong... or the SEF component I used have a flaw. After few days of digging I found that the issue has a much simpler cause.
Lost admin password - reloaded
Did you manage to lost your password? Worst, maybe you lost the Super Administrator password? And for some reason you can't use the retrieve lost password functionality of Joomla... If you use Joomla, if you forget your password you could just simply click on the "Forgot password" menu, and the new password will be sent to your email address. But what if you can't remember the exact e-mail address, or you have a local, development version and did not have the mailer handy... or your Internet connection is down? Or, worse - happened to me couple of times - you need to overtake a site originally developed by someone else?
MooTools problems after FireFox update to version 18
Lately many of Joomla 1.5 site owners have been experiencing weird Java script errors when tried to use their site with FireFox browser. Receiving lots of request almost simultaneously the first reaction was that some software update caused the problem.
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?
