Hello

Unfortunately for all broken websites the only way to fix is a manual edit
Only if Flexicontent v3.3.11 is install prior to Joomla update ,  then next manual fix will not be needed

To fix website


1. Edit File  administrator/components/com_flexicontent/definecontants.php

At line 63, replace 3.9.99  with 3.99.99 

if (!defined('FLEXI_J40GE')) define('FLEXI_J40GE', version_compare( $jversion->getShortVersion(), '3.99.99', 'g' ) );

2.  Go to Extension/Manage Database and click Fix
3. Then upgrade to FC v3.3.11

Hi

I am still getting error after changing code:

Fatal error: Cannot declare class JEventDispatcher, because the name is already in use in:
ok21\administrator\components\com_flexicontent\defineconstants.php on line 107

Have updated to:

Hi,

I have overwrote the defineconstants.php file from 3.11:
github.com/FLEXIcontent/flexicontent-cck.../defineconstants.php

but the error persists:


Any other ideas?

---

If anyone else is stuck. I reverted to an older version of Joomla by overwriting all the files:

Joomla_3.9.x_to_3.9.28-Stable-Patch_Package.zip
 

Hello

there is 1 more case in IF YOU ARE using master branch (FC v4)
components/com_flexicontent/tasks/core.php
which i have fixed in github

but i suspect the above is not the problem

In your website maybe FLEXI_J40GE is already defined in some custom code ?

Can you can do a text search for
define('FLEXI_J40GE'
in your website to see if it is also defined elsewhere

Hi ggppdk,

Thanks - for the fast response.

I have done a full search and its only that one in defineconstants.php:

if (!defined('FLEXI_J40GE'))   define('FLEXI_J40GE', version_compare( $jversion->getShortVersion(), '3.99.99', 'g' ) );

I also limited it to: FLEXI_J40GE and still only the above.

I haven't tried upgrading my other sites yet. So - not sure if it's isolated to this one or something else.

Cheers,

Robert
