We have got a man to help us moving the template over to our new webside after we have made it from another website but still in WP. Now I cant edit anything. Can you go a look whats wrong? Maybe it has something to do with the plugins..
Switching on the default theme is save, provided everything has been installed properly and no code errors. Please navigate to Appearance > Themes > activate any default theme, check the issue it the problem still exists the reason is plugins conflict.
If the problem occurs only on other themes, deactivate third parties plugins and provide site admin access and FTP
