Have you unchecked ‘Custom Fields’ in the Screen Options panel– top left underneath the Username|Turbo|Logout bitt– on the Posts page?
Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-related problems?
– resetting the plugins folder by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.
I have looked in the Screen Options panel but ‘Custom Fields’ isnt listed! I also disabled all plugins and it still doesnt appear. Like I said the custome fields do appear when i post a Page.
Did you try the other 2 options I suggested?
Bingo! Removed the inactive plugins and the Custom Fields appeared again! Many Thanks!
