We are getting the same in our error logs.
Our client reports the following:
“I’m having trouble again after editing regular pages and it seems to be breaking the website, though it only breaks it for about 5-10 minutes. I edited the same page again and it seemed to work fine. However, after going to view the post, I clicked the edit button from within the page, and just get a white screen with ‘error’
After the first test, I could get both the Home page and some interior pages to load, but I couldn’t get the blog page to load, the admin area, or the other main pages along the main navigation. Hector, Steve, and I tried Chrome, Firefox and Explorer, and I cleared cache in all of them. Firefox and Chrome gave us just the “error” message. IE says its HTTP 403 Forbidden. After about 5 minutes, all the pages loaded again.
For the second test, I was able to break the site at 10:23 am and this time I couldn’t load anything (white page with ‘error’). Refreshing the site at 10:38 loaded everything again.”
Hey,
The “error” message is confirming that you’ve been locked out due to too many 404s. While I understand it can be annoying, that means the feature is functioning correctly. You can learn more about this in the 404 section here – Common Issues
Thanks,
