Getting Ready To Update To J6, Disabled Compatibility Plugin And Getting A Errors
Mike Underwood
The site is at https://zanipro.com/new/
Before I attempted to update the site I updated both HelixUltimate and the Free version of SP Page Builder to the current version. I then went to the Joomla Update, and saw that I needed to disable the compatibility plugin and did so, once I did that the site is failing with the errors below.
Display Errors is enabled in the configuration.php and when you go to the site you will see the following on the front end:
Attempted to load class "Helper" from namespace "HelixUltimate\Framework\Platform". Did you forget a "use" statement for another namespace? Symfony\Component\ErrorHandler\Error\ ClassNotFoundError in /home/cdproc5/zanipro.com/new/templates/shaper_helixultimate/error.php (line 19) use Joomla\CMS\Uri\Uri;use Joomla\CMS\Language\Text;$app = Factory::getApplication();$doc = Factory::getDocument();$template = Helper::loadTemplateData();$params = $template->params;$fontCSS = '';function addGoogleFont($fonts){
IN the backend I am seeing: An error has occurred. 0 Class "JPlugin" not found Call Stack

I am not sure what is going on, as the errors look to me to be with Helix and/or Page Builder and I am not familiar with seeing this error related to either of these.
If you could take a look please.
Thank you, Mike

Accepted AnswerIt was the latest version of both HelixUltimate and SP PageBuilder Free. I uninstalled SP Page Builder Free and disabled the compatibility plugin. The site then stayed up and I upgraded to Joomla6, then re-installed SP PageBuilder Free and the site is fine now.
Not sure why I had to do that, as I have never had that problem before updating a site to J6 with SP PB installed.
But it works now and all it good.

Accepted AnswerHello Mike,
Thank you for reaching out to us.
From the errors you shared, it appears that the issue occurs after disabling the compatibility plugin while preparing to update to Joomla 6. The errors indicate that some classes used by Helix Ultimate and SP Page Builder are not being loaded properly once the compatibility plugin is disabled.
At the moment, Joomla 6 removes several legacy classes (such as JPlugin) that older extensions may still reference. If the compatibility plugin is disabled before all extensions are fully compatible, it can result in errors like the ones you are seeing.
We recommend the following steps:
- Re-enable the Compatibility Plugin so the site functions normally.
- Make sure you are using the latest versions of both Helix Ultimate and SP Page Builder.
If the issue persists even after updating everything to the latest versions, please let us know and we will be happy to investigate further.
Thank you for your patience.
Best regards,
