I am having issues saving with upfront editor (using the spirit theme) – I only started with upfront last week – I did a website (www.hardhillexecutivetravel.co.uk) with it (which had a previous theme) – I have went back to edit it but the save is – inconsistent (mainly NOT working) – I am using IE 11.20 and I a DEFINATELY using the SAVE on the left hand upfront dashboard and also trying to do the save via a right click – BUT changes are nearly always NOT saving (but occasionally do)?
