After solving couple of times the "500 Internal Server Error" problem as described in a previous post, I received another complaint from one of my clients I host:
"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.
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.
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.
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?
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?
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.
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).
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.
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:
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?
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!!
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?
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.
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?
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.
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?
When one needs something, usually want it fast' and with large, complex Joomla sites that may be a problem. Sometimes the search takes... okay, not forever, but long enough to think about how you can give it some extra speed. Here are some tips and tricks to accelerate Joomla search speed:
Beginning with Joomla 1.6 it's possible to lock anyone out of the back end of the website — including Super Users with Admin permissions — by setting the Site Admin permission to Deny. And this is something you can do accidentally against yourself by playing with the permissions without knowing how exactly these settings are working. That can have unpleasant side effects especially at the Super User group or at the Manager or Administrator group level. If Manager or Administrator is set to Deny, the Super User would inherit Deny from these groups, even if the Super User group is set to Allow.
We all know that Joomla is all about collaboration. And anyone who had set up at least one instance of Joomla knows, that there are multiple levels of access in Joomla, among them one called Author who is supposedly able to submit an article to a Joomla site from the frontend.
