Janekivi, can you give me the time stamp dates for the original files that get switched out by your Menu 5 for 2.3.0 so I can see if any of those have changed with 2.3.13
All my files in camera have one 2014 midsummer time +/1 minute diference...
You must compare your files and look what time they all have and what is newer, what updated lately.
Compare contents and there may be always something new what disabling to toutch some files.
I think as long as you do not toutch windows you can use ftp to restore.
My menu is working in my 2.3.0 E4 and made for it. This is your playground, give a try
or not : )
And yes, with multiple files may be problems.
There is not much free disk space in camera and it loads files if they are renamed, for example conf.cfc
He is loading files what in that place where he must load something whatever the name is. And menu is
defined by default design_ui*.xml facet_*.rcc - that is another point what you must notice.
