Hey there, Max! Just wanted to chime in since I'm testing CC6 this weekend on a staging site/test migration from Joomla 3 to Joomla 4.
I installed the latest version that you emailed to us.
First, I've tested this both ways, upgrading prior to migration to J4 and after.
In each case, I've gotten multiple 500 errors, and I've isolated it down to CC6. So, the extension we love is currently (temporarily) holding the site hostage.
(Lol -- I'm sure this is a simple fix, but I don't know how to do it myself.)
Here is the message (in both Firefox and Chrome):
Attempted to call an undefined method named "isAdmin" of class "Joomla\CMS\Application\SiteApplication".
(Firefox message)
Call to undefined method Joomla\CMS\Application\SiteApplication::isAdmin()
(Chrome message)
The file that triggering these errors is:
/plugins/system/chronoengine_gcore2/chronoengine_gcore2.php
So far, the errors have pointed out Line 17 and Line 30 in that file. I could get past the first error (Line 17) by changing
if ($JApplication->isAdmin()) {
to
if ($JApplication->isClient(‘admin’)) {
but Line 30 is different. I'm not a hard-core coder, so I don't want to do any major tweaking on your great product. Also, there may be more places that will/would trigger this error, but we haven't been able to proceed past this point.
Any help or guidance you can provide would be greatly appreciated!
