For any further help please use the forum

Closing this as it is not a joomla issue. @HerBauer as your name seems to be german, you also can have a look here https://www.j-over.de/de/template-overrides.

In my opinion it is joomla issue and it should be open for discusion why joomla community don't have flat view in joomla?

@chmst as your name seems to be german, you also can write in german if you dont want to use english

Whick file is responsible for edit view in joomla Protostar template? Couse its seems brian provided outdated information not relevant to joomla 3.9.23 Protostar template?

there is no file name or path in joomla 3.9.23 Protostar templat to find this file whick brian mentions in his links

In github everyone writes English (or kind of ... ;) )
The file is not in protostar as long as you don't make an override of the file components/com_content/views/form/tmp/edit.php in your template.

@chmst danke, so whick code removes the tabs in edit.php ?

@HerBauer please stop the discussion here.
Brian is fully right, this isn't a discussion forum, it's a core issue tracker. And it was already said that it is not a core issue. And you even got pointed to the right solution for your issue (which also isn't the purpose of this issue tracker).
