Hello,
Yes, it was a restriction from Zyma. They had been experiencing brute force attacks so disabled access. They failed to tell me!
Thanks for your help.
Thanks for your response.
I have no security plugins but disabled all plugins anyway to make sure.
I have also tried disabling the themes.
I have tried deleting .htaccess
None of the above have helped.
I have unlimited hosting with Zyma.
