    I have got the same, but with a slightly different error!

    Fatal error: Cannot redeclare wp_convert_bytes_to_hr() (previously declared in /home/guusterb/domains/guusterbeek.nl/public_html/wp-includes/deprecated.php:3364) in /home/guusterb/domains/guusterbeek.nl/public_html/wp-includes/media.php on line 1146

    Thanks Govpatel, I will try and replace the files. Should I install the previous Worddpress version just to be sure?

    Cheers

    You will need switch to default theme

    I can't access the admin of WordPress.. So I can't do anything. What about you lawbla ? Did you manage to fix it already?

    The only thing I can do is access my ftp and try to follow your instructions and hope it will work again.

    Using ftp rename your theme in wp-content/themes folder so that default theme opens.

    Pardon me, I am a bit of a WordPress noob. So, I should rename the folder of the theme I am currently using? What happens? WordPress automatically changes to the default theme? Or should I edit a php somewhere? Thanks for helping me out btw. It's appreciated a lot!

    I just tried renaming the theme folder. And nothing changed, still the same error.

    I've seen others having similar errors in the past during upgrades when a function moved from one file to another during the development process. The best and easiest thing you can do is replace the wp-includes and wp-admin folders with fresh copies, as govpatel suggested.

    Thanks for the tips guys. I tried to replace wp-includes and wp-admin and now the error changed a bit. But that's the only thing, no response from the admin though.

    Fatal error: Call to undefined function get_post_format_slugs() in /home/guusterb/domains/guusterbeek.nl/public_html/wp-includes/theme.php on line 1264

    Try re-uploading all files & folders - except the wp-content folder - from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    Did it! Thanks guys. Just to let you know. I forgot to replace the files that were in the main folder of the new wordpress update. Also I changed the name of the theme folder I was using. After replacing the files it asked me to update and voila, we're up and running again. Thanks for your help guys!
