Try:
– switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.
– resetting the plugins folder by FTP or phpMyAdmin.
– 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.
– running the upgrade manually via wp-admin/upgrade.php
Thanks for your reply, but I can’t get into my dashboard. I get a:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘_show_post_preview’ not found or invalid function name in /home/w8400396/domains/bekwameminnaars.nl/public_html/wp-includes/plugin.php on line 406

when i surf to /admin
Now try reading my post above. None of the suggestions made require you to login to your WordPress dashboard.
Follow esmi’s advice BekwameM. Also try the codex
http://codex.wordpress.org/Login_Trouble
This is pretty much what esmi has explained with a few extra bits.
I was having a problem logging in yesterday and I had to replace my login.php file with a new version from a fresh download of wordpress
Apologies. I did read it, but it seems I’m not knowledgable enough on the subject. Will take your suggestions to by host.
Hi I really really need someones help. I have these two warnings:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘_show_post_preview’ not found or invalid function name in /home/askwarok1/amandaskwarok.com/wp-includes/plugin.php on line 406
Warning: Cannot modify header information – headers already sent by (output started at /home/askwarok1/amandaskwarok.com/wp-includes/plugin.php:406) in /home/askwarok1/amandaskwarok.com/wp-includes/pluggable.php on line 874
My hosting site automatically upgraded me to php5 and this is what happened.
I have already tired:
-everything listed by esmi’s advice.
-I tried reverting back to the old php 5.2
-I updated and reloaded the new wordpress files (includes and admin)
-I deleted and reuploaded wp-login.
-I deactivated my plugins content-plugins
I feel like I really tried but to no avail…
I’m a freelance designer so you can imagine how stressful this is as this is my job…
If anyone could help me I would be so so greatfull! 🙂
