400 Bad Request Error

  • When I try to update a page, I’m sent to the page that says: 400 Bad Request Error.

    I tryed out a lot of things: clear cache of browsers (firefox, ie and chrome), disable all plugins, ipconfig/flushdns in my command prompt (in my Windows SO), switch themes and nothing works.

    I can access the site, and it’s ok. I can create a page, it’s ok also.
    This problem only happens when I try to update a page.

    I don’t know what I can do, please help me!

    Try:
    – Flushing any caching plugins you might be running, as well as server and/or browser caches. Also, any op cache or content network cache, as well as Cloudflare, clear those caches.
    – deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
    – If you can’t get into your admin dashboard, try resetting the plugins folder by FTP. Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder (if you have created such folder). The easiest way is to rename that folder to mu-plugins-old.
    – switching to the unedited default Twenty Fifteen theme for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). If you don’t have access to your admin area, use FTP , or your web-host’s cPanel or whatever file management application your host provides. Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it.
