Hello,
Steps 4 and 5
[4] Go to BackEnd->Components->sh404SEF->ControlPanel->Configuration->sh404SEF_Configuration->ByComponent
[5] Set Vehicle Manager to [Use sh404SEF plugin if available]
are not actual for last version of plugin, which you have.
You instal SH404SEF component and install plugin, as you made. Then in Joomla Global Configuration set in SEO Search Engine Friendly URLs - NO and in sh404SEF set Enable URL optimization - YES.
Before you had for example URL:
localhost/~taras/Update/index.php?option=com_vehiclemanager&task=alone_category&catid=47&Itemid=141
with plugin
localhost/~taras/Update/index.php/141/alone_category/47/Sedan.html
Move in this way.
Thanks,
