Support » Fixing WordPress » Warning: Class __PHP_Incomplete_Class has no unserializer

  • Someone commented that they keep seeing PHP code on my the home page of my blog (simplykk.com for reference). The code looks like this:

    Warning: Class __PHP_Incomplete_Class has no unserializer in /home/content/p3pnexwpnas10

    and then continues on with numbers. I have not personally seen this show up with my browser, but it is a constant issue with some of my readers.

    Please help! Do I need to clear my cache? I am using WordPress 4.7.1 with Go Daddy.

    Try:
    manually resetting the plugins folder by FTP/ SFTP (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause. 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 Theme (Twenty Sixteen, etc.) 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/ SFTP , or your web-host’s cPanel or whatever file management application your host provides (no Dashboard access required). 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.
