After I installed the rokstories module from www.rockettheme.com, if I clicked on one of the articles (rokstory), I would get a page with the article on it but with the following error (3x) above it:

Warning: Invalid argument supplied for foreach() in /home/.../components/com_content/helpers/route.php on line 106

After googling I found an unlikely solution which is becoming typical of Joomla. I hadn't switched the site to SEF friendly yet but I did this just to follow along with the solution. You need to make a menuitem to just one of the articles. I have a menu called "unused menuitems" (named unusedmenu), which isn't displayed anywhere on my site. I'm guessing the reference in the database is what corrects this.

 It took a few google searches until I could find out how to change the default weblinks order.  A lot of websites showed how to do this via the admin back-end panel in the advanced configuration... I can't see this panel, there is no advanced parameters under a weblinks category.

The issue is that suppose a menuitem links to a category of weblinks, the default sort order (as in the first time you view the page) is the order in the admin panel (not even by most recent).  I'm going to show you how to do this by title in ascending order without installing any 3rd-party extension as well as by any of the database values used by each link.

If you are in the administration panel and you are editing your weblinks and you come across this error:

"404 - An error has occurred. 

Joomla! was unable to locate the stated resource."

 By adding the following line to your LocalSettings.php file, you will be able to log everything that WikiMedia does:

$wgDebugLogFile = '/home/username/public_html/wikidir/logfile';

IMPORTANT NOTE: The path above should be the exact full path to the wiki directory under your account.

 The issue here is that you have added all your banners, divided between clients and categories and you're looking for a solution which doesn't involve installing a 3rd party applicatoin.

 Unfortunately the Joomla banner module only supports alternating between banners of either the same client OR the same category.  The setting is in your Joomla > Module Manager > Banner... What I do is I don't select a client but instead just select a category.  Set it to only display 1 banner at a time.  

If you want other categories to display, consider setting categories as vertical, horizontal and square banners.  This means that you can have 3 modules each displaying banners from each category and position these as appropriate.

This took me a whole afternoon and involved a lot of hope as I browsed the Internet and no one seemed to have done this before.  Fortunately, MediaWiki extensions are easier to write than Joomla CMS ones :c)

This article shows you how to get your MediaWiki system to display your Camtasia Studio SWF files in it's articles.

Why Camtasia when there are other free options?

We tried lots of FLV players that were usually branded or not free.  These were awkward to configure a full screen button on the controls and do basic customization.  Our screen recorder was also not displaying the captions of the video unless it was an AVI file that we converted to FLV.  The quality was horrible.  Then we moved to Camtasia Studio where their videos were displaying in good quality but as SWF files.  This extension includes the default settings for "ExpressShow" in Camtasia Studio.

 This is related to the issue of renaming yourdomain.com as your title page in phpBB3.  

You need to login to the phpBB admin control panel (ACP).  On the General tab, look under Board Configuration and click on 'Board Settings'.  The Site name is the first field in the right panel.

"OK this should take just a few minutes..."

I've written this because I spent all night on setting up a "quick" demo resulting in a quick 1 hour nap before having to go to my day job...  It sounds straight forward because both phpBB3 and RocketTheme talk about how to install the RocketTheme templates...  But it's not.  I'm rewriting their instructions here so that I can I do this on other websites:

Important Note:  On Linux (Apache), all file names and folder names are case-sensitive, so phpbb3 is NOT the same as phpBB3.  Bear this in mind during the installation process.

The Issue

Basically that you've installed JoomlaEZ's ReCaptcha Integrator plugin to protect your forms ("type two words" captcha) and then installed K2 Comments to use it's own ReCaptcha.  If you try adding a comment, you may get something like the following:

Fatal error:
Cannot redeclare_recaptcha_qsencode() (
     previously declared in /public_html/plugins/system/jezReCaptcha/recaptcha-php-1.10/recaptchalib.php:47
)
in /public_html/components/com_k2/lib/recaptchalib.php on line 67

I've managed to fix this in my site. Because you already force the recaptcha feature in your registration form and contact form (on this website I just went recaptcha-happy), then there are some settings you need to change in the plugin options:

• Inclusion Syntax = NO
• Auto-verify =YES

Update 16.NOV.2009

I don't see this supported anymore so I wouldn't recommend using the JezRecaptcha plugin.  In fact I'm not impressed with Recaptcha as it's sound alternative doesn't work and the text form is hackable.

I will be changing this over throughout the site... I may keep recaptcha for the comments feature on K2 articles but it should be considered low security.

Old Server

mysqldump -u root -p wikidb > wikidb.sql
tar -cvf wiki.tar wiki   ;this is the wiki folder on document root

New Server:

create database wikidb;  this is inside mysql, Note that both mysql versions should be same.
grant create, select, insert, update, delete, lock tables on wikidb.* to wiki@localhost identified by 'YourPassword' ;

MediaWiki Upgrade

copy all the new files to wiki folder and then run php update.php from maintenance folder after updating AdminSettings.php

It's been difficult to find an easy solution to hide menu items from registered users. Finally, I found a solution that works 100% for me using the MetaMod tool without using any template hacks. The instructions on the metamod page are very vague so I wanted to make it bit more in-depth for this specific use. I'd love to hear if this helps you. Let me know if you find any mistakes and I'll be sure to fix asap.
