Hi sorry for the delay – had issue at work –
I tried with Chrome instead of Safari:
Deleted the plugin and installed/activated again via store in clean 6.5 install
Still get the error saving the ABS code in Chrome
switched to Win10 on Edge browser – on the vanilla 6.5 / re-installed 6.5 and same error
very strange I think.. and wonder if it has something to do with my hosting provider and “shared hosting” – haven’t had a problem with other plugins
my provider is JustHost
