Strange behaviour

I wanted to create a new sort of content today and I couldn't find any tab to create it in the content administration node.

This is strange because I installed the module long ago and created three new types of content then and they still exist and work without troubles.

I guess it could be another module which messed up something bot couldn't say which.

Another thing: if I go to admin/settings/flexinode all I find is this dialog boxes:

Image processing
Default thumbnail resolution:
Default size of thumbnails: format will be the same as original image. Use just one dimension, and put a "x" to specify height. Examples: "100" for width of 100; "x200" for height of 200.
Imagemagick Convert path:
Absolute path to ImageMagick convert executable. Include the filename at the end.

Anyone has suggestions?
