Not the latest version is installed on your site. You can see it if open the next link:

YOUR_DOMAIN/modules/mod_arisexylightbox/mod_arisexylightbox.xml

replace YOUR_DOMAIN with domain name of your site. Download the latest version of the extension in "Member Area" and upgrade "ARI Sexy Lightbox" module please. If you have any difficulties with it, you can provide temporary access to your Joomla! backend by email and we will help.

OK! I dont know why it didn't actually update when I reinstalled previously but it worked this time and the problem is fixed.

Thanks for your help, it is much appreciated!

Sorry to reopen this thread as I juts noticed another issuw with the html, which doesn't seem to be fixed:
Line 556, Column 50: document type does not allow element "div" here; missing one of "object", "applet", "map", "iframe", "button", "ins", "del" start-tag
<div id="asl4d7c7d67816ce" style="display: none;">
&#9993;
The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.

One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").

This is not extension problem. It is problem with HTML code around plugin code. It wraps with "<p>" and "<span>" tags:



If you use a WYSIWYG editor, switch it to plain text mode and remove wrapped tags or replace it with <DIV> tag.
