RESOLVED about 1 year ago - at 03/21/2023 05:34PM

The recent incident has been resolved and the errors you may have experienced should no longer appear.

A change in rules for a limited set of WAF users resulted in mistaken 403 errors, especially during CMS login and content editing. If you still encounter unexpected 403 errors, please try clearing the cache and testing in an incognito window to confirm it is not a local caching issue.

However, if you're still having any trouble accessing your site, our support team is available to help. Please don't hesitate to contact us for further assistance.
