How is it possible to set in Page TSConfig the default value for "Number of Columns" in TYPO3 V7.6? In erlier versions it was possible with TCEFORM.tt_content.imagecols = 1. If I set in V7.6 TCEFORM.tt_content.imagecols = 1 it makes no different which value is set. There is always imagecols = 2 set.
I have PHP 7.0.7 and use the rendering extension fluid_styled_content (not css_styled_content). Is there something I am missing?
Thanks in advance for your help.
