The next Friday is Vietnamese New Year's Eve. In the next few hours we are going to travel back our hometown and spend the new year holidays with our families.

We will be pretty busy with preparing for new year celebration and going to visit our relatives, so our support and replies to your forum posts, to your emails will be slow, however we will try our best to reply within 24 hours. So please be patient and please forgive us to this inconvenience!

Thank you very much for your support in the past year!

We would like to announce the release of CMDealAggregator 1.2.1.

CMDealAggregator 1.2.1 is just the same to 1.2.0. The only different is 1.2.1 is compatible with Joomla! 3.2.x. Some users reported that they receive "SQL=SELECT Array,Array FROM WHERE `catid` = 0 ORDERBY ordering" error in CMDealAggregator after updating their Joomla! to 3.2.1, CMDealAggregator 1.2.1 is released to fix this problem for future users.

If you have any problem with this new release please feel free to contact us. If you want to upgrade from 1.2.0 to 1.2.1, please note that all the files will be overwritten, so any customization you made will be lost, please contact us for manual update instruction.

DOMPDF is one of many solutions to convert HTML to PDF.

To use DOMPDF with Joomla!, we need to manually download DOMPDF then upload to our Joomla! website's server.

CMExtension packages a Joomla! library extension for DOMPDF which can be installed and removed easily in Joomla! administration area. After install this package, DOMPDF is stored in <Joomla root folder>/libraries folder, now you can call DOMPDF from there and use it for your project.

When new version of DOMPDF is released , our package is also updated to provide you the new code of DOMPDF.

You can download DOMDPF Library for Joomla! here.

NOTE: This package is provided by us (CMExtension). We only creates this installation package for Joomla! CMS, DOMPDF has been developed and maintained by the community at Github. DOMPDF is licensed under GNU Lesser General Public License (

CMExtension is proud to announce the release of CMGroupBuying 2.7.0 with some new improvements:

  • Compatible with Joomla! 3.2.0.
  • Integrate with Disqus comment.
  • Improvements in CM Group Buy template for compatibility with RTL languages.

Since 2.7.0 release, we would like to change the release cycle of CMGroupBuying.

CMGroupBuying is now a big component with many additional extensions and many many features. Thank you very much for all your support, ideas, feature requests! Since the early days of CMGroupBuying, we have 1 month release cycle, every month a new version with improvements, with new features. However, now 1 month is not enough for us to develop new features and test them,  we need more and more time to test them all.

So what and how will we change?

Instead of 1 release every month with a few new features. Now we would like to have a new release in 2 (or maybe 3) months with more new features. We just updated CMGroupBuying Roadmap with new features of 2.8.0 release, we really need more than 1 month to develop and test them before publishing them.

Although we introduced what is new in 2.8.0, other ideas are always welcomed! Please feel free to post your request on our forum, if we have time we will integrate them right in 2.8.0. Please note most requested features have higher priority.

Again thank you very much for your support! If you have any problem with 2.7.0 version please contact us!

Dear CMGroupBuying users,

If you are running CMGroupBuying on Joomla! 3.1.x, do not upgrade to 3.2.0!

Joomla! 3.2.0 will be released in November, it includes new features and changes, there is 1 change that affects CMGroupBuying:  Migrate application classes from legacy JApplication to JApplicationWeb.

If you upgrade to Joomla! 3.2.0, you will not receive any Joomla! message when using CMGroupBuying, eg info message when action succeeds or error message when action fails or when error occurs. You could easily notice this problem when adding a new deal to cart, the message "The deal is added to cart successfully." is no longer displayed.

We are working for CMGroupBuying 2.7.0, it will be compatible with Joomla! 3.2.0.

If you want to upgrade to Joomla! 3.2.0:

- Wait until CMGroupBuying 2.7.0 is out, upgrade both Joomla! and CMGroupBuying.

- Fix CMGroupBuying by yourself (programming skill required). You can refer this commit. In general, you need to change

JFactory::getApplication()->redirect($this->redirect, $this->message, $this->messageType);


JFactory::getApplication()->enqueueMessage($this->message, $this->messageType);


You can use your preferred integrated development environment to search for 'JFactory::getApplication()->redirect(' in CMGroupBuying source code and update them.

Please feel free to contact us if you have any question.
