Moodle 2.3.3+ on Ubuntu server
Changed theme from Formal White to Decaf
Admin users lose blocks on front page (left and right).
Teachers and students still see them. They are also visible when not logged in.
Tried changing back to standard - still happens
Have cleared browser and theme caches and changed to other themes - still happens.
Occurs on both Chrome and Firefox.
It is maybe as if options 'no blocks' is permanently on for admin users in that context?
Maybe this is something [simple] that we have missed - in which case apologies. (it rings vague bells from before but senility is filtering recall and searching has proved fruitless)
