Hi Saguaros,
Yes, one can still create and delete modules. I'm actually trying to understand the cause and solution to my issues with missing 'Menu' modules. As you'll note there are none, yet all the menus still works. As mentioned I'm not one to delete modules (much less 'Empty Trash'; I simply 'Unpublish' them), so it's a complete mystery to me on why the 'Menu' models are missing.
At first I though I might have deleted some files by accident, but when I changed the database back to the Quickstart default all the 'Menu' modules reappeared; thus my inclination this is a database issue.
If I can't discover the cause, I'm at least very eager to explore potential solutions, amongst them:
1) Is there a way for me to 'Upload' and ultimately mix my current database with the default database so that the missing 'Menu' modules reappear?
2) If #1 is not possible, is there a way to upload specific database tables related to the missing 'Menu' modules?
3) Is there any other cause/solution I should be exploring?
*I'll separate and write a new post about the 'Search' module as it seems unrelated to the database.
