I stumbled on this thread whilst looking for the answer to why I was getting an error message "Error while parsing the toolbar configuration file/Configuration/AutoConfigure/Simple.config.

 

In my case it was very simple; In the call to the editor in my php script was the line

 

$editor->AutoConfigure="simple";  //Select Toolbar

 

but should have been

 

$editor->AutoConfigure="Simple";  //Select Toolbar

 

i.e. with an uppercase 'S' at the start of the word 'Simple'.   Whatever is specified here has to match exactly (case sensitive) with  a filename in the CuteEditor_Files/Configuration/AutoConfigure folder - the '.config' extension to the filename is added for you.
