Slow admin

I reported getting 405 Not Allowed nginx/1.12.2 Errors and took it up with the hosting they provided me access to the errors logs that do not show anything

I had issues with all posts and pages now it is just on the front page I have been stripping things out to see if I can trace the issues today the 405 error happened again and the front page in admin when you save takes ages or times out
