Switch to the TwentyEleven theme (and make sure you’re using the latest version thereof).
What theme is this? Can you link to it?
I haven’t got access to admin panel. If I FTP can I delete the theme I am using and will it go to default. Or is there a way to activate the Twenty Eleven Theme? Thanks for all your help.
Yes, if you delete the theme it’ll revert to TwentyEleven.

Two things to try.
1) Manually re-install WP
2) Delete the theme folder for whatever theme it was you were using.
Thanks all done. Cheers for your help.
hello,
I’ve found another solution.
I wanted to stay with Back My Book theme, so, I’ve checked what had happened.
In file “../wp-content/themes/back-my-book/admin/custom-header.php” there’s a declaration of a class Custom_Image_Header. It overlaps class that already exists in WordPress Engine – that’s the reason of fatal error.
So, I’ve replaced name of this class to Custom_Image_Header_BMB (and other occurences – 3 occurrences all together in custom-header.php file), then I’ve renamed call to this class in “../wp-content/themes/back-my-book/functions.php” file.
Line number 98:
original:
————-
$GLOBALS['custom_image_header'] =& new Custom_Image_Header($admin_header_callback, $admin_image_div_callback);
changed to:
————-
$GLOBALS['custom_image_header'] =& new Custom_Image_Header_BMB($admin_header_callback, $admin_image_div_callback);
It worked for me. You can check it at http://henrykbaranowski.pl/
I’m not a programmer, only ‘home-made screwdriver’ ;-), so, if someone can check if that’s all – I’d be very glad for feedback.
Cheers,

asceta,
Thank you for your post! I also did not want to lose the Back My Book theme, and am very grateful for your insight. I’m not a programmer either and was at a loss.
I had to change the name of the custom_image_header line on a few other lines in functions.php, but after I did that – and after I re-activated all my plugins, all the error messages went away!

Solved my problem. Kudos!
Thank you, Asceta. This fix worked for me.
Took a few attempts as Dreamweaver didn’t seem to like me trying to directly edit the files on the server, but once I chose to edit my local files instead and then PUT them on the server, it worked first time.
Brilliant!
