All the extensions are up to date but, for a reason I've not been able to understand, the joomla automatic upgrade doesn't work and the final result is a blank page.
Installing from an up to date backup, I've tried numerous time disabling extensions one by one but no way.
So now I'm trying to begin with a clean j3.41 with f2cpro 6.10.0 and so I need to transfer content from the j2.5.28.
First issue, when trying to import f2c content type the result is :
The version of your component (6.10.0) and the version of the component that exported the Content Type (4.9.0) are incompatible.
Is there a way to do it ?
