change order number format

[serge-web54]

hello, i migrated an 1.5 site to j3 for a personnal business
the orders were following as this : 132, 133,134 ... aso
now with vm3 it is randomized
i need to have the order numbers following
the plugin advanced order number from opentools is not maintainde and i have this error when installing :

Fatal error : require(): Failed opening required 'JPATH_VM ADMINISTRATOR/plugins/vmplugin.php' (include_path='.:/usr/lib/php7.4') in /homepages/24/d220609846/htdocs/clickandbuilds/Joomla/RC-Collector/tmp/install_60be0e85bdf44/ordernumber.script.php on line 46


so what should be the solution to change the format of the order

[jflash]

For custom order numbers i use same plugin under PHP 7.3 and it works. Why you dont ask from Open Tools developer?

Rheinhold from Open Tools no longer supports his extensions and made them available for free in case anyone can use them.

The extension from iStraxx is supported:

try adding 

VmConfig::loadConfig();

after

require(JPATH_ROOT.DS.'administrator'.DS.'components'.DS.'com_virtuemart'.DS.'helpers'.DS.'config.php');

in  ordernumber.script.php
