If you go to Settings > CMS, nowhere the CMSimple Version is mentioned, so what you are meaning?
I have changed language from Danish to English so it is easier to describe (I cannot attach a screen dump - right?)
My site is www.1951.dk
After login I go to Settings > CMS
It says: You are here: Edit CMS configuration. Next line - in a frame - says: Version- and Update Info >>.
I can also go there by Settings > System Info
Installed CMSimple Version:
c CMSimple 4.7.2 Released: 2017-05-07
Newer version is available: Link to Info and download
c Link to PHP Info >> (opens in a new window or tab)
There CMSimple 4.7.2 is running.
So the update has not been done. Have you uploaded it to the right place (CMSimple Root folder)?
There definitely no (correctly) update has been done. After a correctly update a file "setup.php" should be in the CMSimple Root folder.
Seems you have uploaded the Update to a wrong folder, maybe to CMSimpleRoot/cmsimple/,
