[TYPO3-Solr] solr 3.0.0 problems after upgrading to typo3 6.2.4

This issue has been resolved! In the end I don't know what was the 
reason, because it disappeared after one of several typoscript fixes 
done on the page. These were mainly FAL compatibility fixes, but also a 
few tweaks in solr settings and also FAL fixes for a few DCE extension 
elements.
I wish I knew what was the main culprit here...

Sorry for taking your time, but the error message seemed to be related 
to solr...
