Hi,
in frontend editor mode of a text box the "Content" field is not visible any more.
So I'm not able to edit the text.
It worked very well - but I changed some settings.
I also used the jspeed-Plugin.
I can edit the contend field in normal editing mode.
I use:
SP Builder Pro 3.8.3
Joomla 3.10.5
Template Finion
JSpeed Plugin
