Hi,
Hmm, please try:
1/ Deactivate all plugins and check it again. If it work, let's enable each plugin to check what's plugin caused this issue.
2/ If point 1/ still doesn't work - let's contact with your hosting provider and ask them about this. Seem the hosting has been blocked for edit htacess file or something else similar..
Best Regards,
