Frequently Asked Questions about Sliders

The {slider} tags are not being converted

The Sliders plugin is not published

Check if the Sliders plugin is published. Go to Extensions >> Plugin manager and search for the system plugin System - Regular Labs - Sliders. Then publish it.

There is markup on the {slider} tags

It is fine to give styles to the titles within the {slider} tags, like: {slider My Title}
But giving styles to other parts of the tag, or the entire tag, can cause problems, like: {slider My Title}

If you have copy/pasted code directly into your editor, you might also have copied along hidden HTML tags. So this will also cause the {slider} tags to break:

{<span>slider</span> ...}

Remove the extra styling or other html tags around and in the {slider} tags that might cause problems.

Sliders are not working on all browsers

There are javascript errors

Javascript errors might and usually will cause the sliders to disfunction. You probably have a Mootools or jQuery conflict on your site. This often happens if multiple Mootools or jQuery scripts are loaded.

Take a look in the sites output html (CTRL+U) to check this.

For more details about the javascript error(s), you can use Firefox with the Web Developer Toolbar, Inspect Element console in Chrome, or any other browser with a javascript debugger.

Sliders are not working on Internet Explorer (but are working on other browsers)

There are problems in the html output structure of your website

Internet Explorer is pretty picky when it comes to html. It will not handle invalid markup gracefully.

Check if you have unclosed html tags in your content (see the html view in your editor), like divs or spans that have no closing tag, or lost closing tags without opening tag.

You can check your page for html errors on:

Sliders with special characters are not working

You probably have a plugin installed that tries to optimize your html.

Extensions like 'RokBooster' and 'Content Optimizer' try to fix issues in your html. However they also mess around with the urls.

The thing that causes the issue is that these extensions url-encode special characters in urls. This is not good, seeing nowadays urls with special characters are and should be no problem.

So you will have to disable/uninstall these extensions to be able to use special characters in Sliders.

Another solution is to give the slider an alias without special characters, like:

{slider title="Ṩῥἕcịᾳḻ ḈĦẚrḯḉṯɇṛş" alias="special-characters"}

The slider title is showing in the content area

The slider title is also placed at the top of the content, but hidden. This is done for SEO purposes and to accompany the responsive view feature in the Pro version.

If you are using custom css styling, then your stylesheet probably doesn't have the css to hide the heading yet.

Simply add this css to your stylesheet:

.rl_sliders-title {
	display: none;

Will Sliders work with a Bootstrap 4 template?

Tabs (and Sliders and Tooltips) for Joomla 3 use and rely on the jQuery and Bootstrap scripts (and partially css) that comes with Joomla core.
So that is jQuery v1.12.4 and Bootstrap v2.3.2.

Bootstrap has basic tab, accordion (slider) and tooltip functionality which these Regular Labs extensions extend.

Many of the newer templates (especially the frameworks) do not use what comes with Joomla and load their own versions of jQuery and Bootstrap.

With Bootstrap 3 pretty much everything keeps working. You might need to tweak some styling.

With Bootstrap 4 the javascripts and the tab and accordion functionality has changed, causing stuff based on the older versions of Bootstrap to fail.
In some cases you can 'fix' things by overriding css to force stuff to hide/display based on different classnames than the 'active' class, for instance.
But in other cases - especially when the template loads extra scripts further changing the Bootstrap functionality - it is not an easy fix.
Then you would either need to write custom javascript to over-override functionality. Or just accept that it is incompatible and look for a different solution.

There are no plans to change the reliance on Bootstrap 2 (which comes with Joomla core) for the Joomla 3 versions of Tabs, Sliders and Tooltips.

There are plans to rewrite these three javascript-based extensions entirely for Joomla 4, making them no longer reliant on either Bootstrap or jQuery.

Doing so will mean that updating Joomla 3 to Joomla 4 will probably break your customizations, as the scripts and css styling will be completely different.


How can I install/upgrade Sliders?

You can either install Sliders by using the core extension manager available in the Joomla! Administrator Control Panel, or by using the powerful Regular Labs Extension Manager.

Note: When updating Sliders, you do not need to uninstall it first. The package will update all the files automatically.

How can I uninstall Sliders?

You can either uninstall Sliders by using the core extension manager available in the Joomla! Administrator Control Panel, or by using the powerful Regular Labs Extension Manager.

If you no longer use any Regular Labs extensions, you can also uninstall the Regular Labs Library plugin by using the Joomla! core extension manager.

What are the minimum requirements?

Sliders will only work correctly if your setup meets these requirements:

  • Up-to-date version of Joomla:
    • Joomla 3.9.0 or higher
  • PHP 5.6 or higher
  • MySQL 5 or higher

Important: I can only provide support for setups that:

  • meet the above requirements;
  • do not have extension files or Joomla! core files which have been altered in any way.

Where can I download earlier versions?

You have access to all previous free versions of all extensions on this website.

If you have a subscription to an extension, you can also download any previous pro version of that extension.

If you do not have a valid subscription, you can download any pro version that is older than 1 year.

You can find old versions in the changelog.

Note: Please note that I am unable to provide support on old versions! (whether you have a subscription or not).

How can I downgrade to an earlier version of Sliders?

If for some reason you need to install an older version, it is best to uninstall the extension first.

You will also have to uninstall the Regular Labs Library system plugin.

After that you can simply install the older version zip file using the Joomla! installer.

Note: Please note that I am unable to provide support on old versions!


Under what license are Regular Labs extensions released?

All free and paid Regular Labs extensions are released under the Open Source GNU GPL v2.0 license.

See the Terms & Conditions for additional terms.

Regular Labs Library

What is the Regular Labs Library?

The Regular Labs Library is a Joomla! library and system plugin that is installed along with every Regular Labs extension.

This plugin contains all the common functions and language strings that the Regular Labs extensions use.

If you use any Regular Labs extensions, this plugin must be installed and published. They will not function correctly or they will not function at all without it.

Do I still need the NoNumber Framework plugin?

The NoNumber Framework has been replaced with the Regular Labs Library.

It is however not possible for my installer to check if a user has any custom code (in custom extensions, overrides or templates) that is using and relying on functionality from the NoNumber Framework.
This is the reason the NoNumber Framework does not get uninstalled automatically.

The NoNumber Framework can safely be uninstalled if your do not have any custom code using it.
