500 Internal Error when saving an article - reloaded
"I also cannot save the articles and here is the error I got 500 - An error has occurred!"
Easy cake - I was thinking, but after checking his account, discovered, that all settings described on that article (namely the collation settings in database) where correct.
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.
Add article title to Read More links
the competition for SERP's (Search Engine Ranking Positions) is fierce. The slightest advantage you can gain can make the difference. Good navigation is key here - and part of this is to give some extra info to your visitors of what they will see if they clicking on a given link. Adding the article title to your Read More links is a way to make this happen.
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?
Blank page when accessing Joom!Fish
It's weird and scary - in a perfectly functioning Joomla site I installed one of my favourite components, Joom!Fish - remember, I'm the multilang guy - and all I got was a blank screen. Obviously, something gone south... but what?
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.
Can't login after moving to new server
If you search on Google for the term "joomla can't login after moving to new server" - or something similar, you will get more, than 1 million hits for most of the combinations.
So, you aren't alone. And there are plenty of suggestions, on what might gone wrong and how you might find that, and there are verious fixes. But what if you moved the site to another domain? From development server to it's final place? This is a subject wich is rarely touched by those advices.
Cannot modify header information - headers already sent
This warning message is produced by PHP if a program attempts to send an additional HTTP header after the separator (and hence all the headers) has already been sent. In the HTTP protocol a server response consists of a group of headers followed by a body, separated by a single blank line (i.e. a line containing only a carriage-return).
Change the default Joomla database prefix
Every hacker in this world knows, that by default all Joomla database tables have the "jos_" prefix. Is that well known, than even automated defacing scripts are using this, and there are a lot of "tools" which are capable to automatically probing your site having this presumption built into them.
Change your database password while having no downtime
Changing your database password is something you rarely need, but then you need it immediately, and with the lowest possible downtime. Why you should do that, in first time? Hm, there are many reasons/situations when you should consider changing your database access data ASAP:
- You just got hacked
- You have decided to end the business with your current developer, and you aren't sure that he's a trustable person
- You have a good habit of changing all your passwords regularly
Debugging your own code
If your read this, then you might have playing with some code already - and as you know, nobody is perfect... all we make mistakes. But how you can find yours?
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!!
Dynamic vs. Static URLs
Joomla, as a PHP/MySQL powered solution is inserting the content into a webpage by way of a script. This type of site is considered to be dynamic. The advantage is obvious - that's why you and me have been chosen Joomla Tongue out. But what's the drawback?
Enable Content History in Joomla 3.2
For any website administrator, having a content version history is an important asset. For Joomla, until recently, you had to find and install a third party add-on. But not anymore, finally content versioning is part of Joomla since Joomla 3.2.
Enable HTTPS and make your entire site secure
Life is full of surprises. One of these days I got a job offering with a consistent budget, one of my former clients approached me to "make his site secure". I said yes, but when turned out what he wanted in fact i had a surprise: he wanted nothing else, just to make the browser warning about "unsecure site" go away. He actually purchased a security certificate and hired someone to install it onto his server - with no success.
Enhanced readmore links
The default Joomla "Read More..." link is fine... but as always is room for improvement. Especially SEO wise, but not only. How about to have a more descriptive and compelling "Read more..." link, complete with the article title for example? Ye-ye-ye, you can right now use sh404SEF for all Joomla flavors, but what if you don't have it?
Enhanced User Profiles in Joomla 1.7+
One of the problems many users are facing when start they Joomla based site is, that the user information Joomla collects during registration is scarce - username and password often is not quite enough for their purposes. And the first reaction usually is to install a community solution, like Community Builder, JoomSocial or other, fancy user management tool - a sledgehammer to crack a nut.
Finding module positions on a Joomla 1.7 page
In the Joomla 1.5 world things where relatively simple: you just added "&tp=1" to the live site homepage's URL, and the available module positions where shown, with a red border and the module position's name in the top left - unless the template's author didn't applied some tricks from preventing you doing that. But what about Joomla 1.7? Anyone tried to do the trick even on a default install can see, that the trick apparently does not works here. Why?
