call to a member function get() on null Topic is solved

[bdames]

I upgraded my Joomla site to 4.4.0 yesterday which all went fine but I now get the following error on my live site:

'0 Call to a member function get() on null'

I've searched the forums and there are a few hits but not many that have a conclusion (worryingly!) although it appears it might be a template issue?. I've turned on debugging on the site and here's the full details:

Call stack

2 PlgSystemConvertForms->getHelper() JROOT/plugins/system/convertforms/convertforms.php:113

16 Joomla\CMS\Application\CMSApplication->execute() JROOT/includes/app.php:61

I'm running php7.4 and cassiopia and have no issue accessing the admin area of the site.

Any help would be very much appreciated.

Welcome to the Joomla forum!

'0 Call to a member function get() on null'

Call stack
# Function Location
1 () JROOT/plugins/system/convertforms/convertforms.php:447
2 PlgSystemConvertForms->getHelper() JROOT/plugins/system/convertforms/convertforms.php:113

The message originates from a system plugin that came with the third party extension, Convert Forms.

If the message is just a notice or a warning, instead of a PHP fatal error, you get rid of it by setting 'Error Reporting' to 'Simple' or 'None', which is the recommended setting for sites in live production mode. Otherwise, disable or or uninstall the system plugin, if it is not needed.
