Having successfully upgraded to 3.3.9 via Softaculous, the automatic updater failed to initialise to upgrade to 3.4.0, not progressing beyond “Updater is loading”.
Again, upgraded through Softaculous.
Once again, the automatic-updater failed to run to upgrade to 3.4.1, stuck at the same “Updater is loading”, this time with a blue Initialize button. Pressing Next does nothing.
All permissions are correctly set.
