Thanks Esmi,
I decided to uninstall that particular WordPress due to not being able to do anything.
I have in the past been able to have the default on in place of a bad theme…Wordpress used to tell you this was possible, not seen that for sometime now. It was’nt a bad theme as such its just I wanted two sidebars on a theme I liked. With hindsight I should have tested on my tesbed install first.
There was no way back to the dashbord, all I got was the warning error on a white blank page. I tried everything in dashboard but every thing I tried just went to the error page.
I think my theme messing up and not being deletable at host cpanel is down to us able to install themes from the dashboard. When I looked in my host file manager that theme was not there to select.
Anyway this can now be a ‘closed’ topic.
Thanks Esmi
