Installation fails on joomla 3.10

Hey there,

I can't get joomla to instal the new file.
That's the failure report I get:

0 Call to a member function getShortVersion() on null

I hope someone can help as I urgently need the newest version.

Kind regards
Brita

Hello install 3.1.14 or 4.1.2

I managed it. Deactivated the old file and then it worked.

BUT I've another question.
I need new versions of these plugins because otherwise our homepage won't work:

System - Flexisystem, core tasks
System - Flexiadvroute, routing tasks

Can anyone help here?

Sorry i dont understand Can you explain more ?

Our homepage at least needs the plugin Flexisystem core tasks to run. But I need a new version. Ours is from 2009 and I haven't found an updated plugin here.
Without an updated plugin, I wonÄt be able to update to Joomla 4.
