Dealing with the "Call to undefined method" Error in OSMap

One of OSMap users faced the "Call to undefined method Joomla\CMS\Document\XmlDocument::addCustomTag()" error. You may see it trying to view either the "XML" or "Images" sitemaps.

The most likely reason for this error may be one of the 3-rd party system plugins you installed. In this blog post, I'll show you how to find which one of them is the source of the error.

How We Are NOT Responding to COVID-19

How We Are NOT Responding to COVID-19

In the last couple of weeks, my inbox has been over-flowing with COVID-19 emails:

  • "Hey, it's the hotel you visited five years ago. This is how we are responding to the virus."
  • "We sold you some software in 2012. Here is some bland work-at-home advice."
  • "We have no idea why we're emailing you. But our boss told us to send out a virus update."

To be honest, I don't have any great advice at all. We're trying to navigate day-to-day, just like you are. Events are moving so fast that even good advice today is likely to be out-of-date tomorrow.

Listen to the Joomla Podcasts from Watchful and JoomCast

Check Out the Joomla Podcasts from Watchful and JoomCast

If you are a podcast fan, you can find three active Joomla podcasts at the moment.

I'll start with a little self-promotion. One of the three is the Watchful podcast that features myself and Vic from Watchful. Our interviews focus on Joomla agencies: how they manage products, find customers, manage their cashflow and so on.

Another is JoomCast and it's a collaboration between Naveen from Joomdev and Tim from Basic Joomla. They interview people from around the Joomla world.

Also, if you speak Spanish, there's also Mastermind Joomla from Carlos Camara, who gave a great session at last year's Joomlashack Conference.

Your Beginners Guide to Multi-lingual Joomla Sites

Beginner Guide to a Multi-lingual Joomla Installation

If you would like your Joomla site to communicate in multiple languages, you need a multi-lingual Joomla site. In this tutorial, you will learn how to install a multi-lingual Joomla site with dummy content and localized menus.

Once you finish the installation, you will then be able to replace the dummy content for every language with your own.

Here is the process in a nutshell:

  • Get ready for Joomla installation. Firstly, you want to upload and unpack the latest Joomla installation pack to your server and create a database for your Joomla site.
  • Run the installation. Then you want to run the installation process for a multi-lingual Joomla site.
  • Translate the dummy Joomla content and add new content for every required language.

Let's take a look at this process in more detail.

Matomo: The Best Alternative to Google Analytics for Joomla

Matomo: The Best Alternative to Google Analytics for Joomla

Over the last year or so, we've heard from more and more people who want to drop big, centralized services such as Google Analytics

The most common reason is privacy. People want to stop sharing so much data with Google. I suspect this is partly driven by a new focus on privacy and data protection laws. But increasingly, many users just don't trust Google.

Another reason is simplicity. The Google Analytics interface is increasingly busy and people often want easier access to important trends.

How to Upload and Use an SVG Image in Joomla

How to Upload and Use an SVG Image in Joomla

One of our customers asked how to insert an SVG image in their Joomla content. SVG images are great since they retain quality in any screen resolution.

But for security reasons, your Joomla system doesn't treat SVG images the same way as JPG, PNG or GIF. This seemingly creates two problems:

  • You won't be able to upload an SVG image to your Joomla site via "Media" component. If you try, the "Media" component will throw "This file type is not supported." error message.
  • You won't be able to insert an SVG image in your Joomla content items with point-and-click. If you try, you won't see the SVG image available.

In this blog post, I will show you how to overcome both of these problems.
