Thank you so much for your help and advice – I really appreciate it.
I found the “pain in the ****” plugin and deactivated it and all is back.
I have just received a message from the plugin creators advising that a update is available. This update appears to have fixed the problem.
G’day ,
Got the same issue – if you managed to resolve it I would be most grateful if you would share it
Thanks
Norman Holden
