Upgrade problem 4.2.2

[astdirect]

I am having major issues with anyone being able to upload images to the forum. I either get an "undefined" error or when you click upload nothing appears in the post.

I have tried pretty much every variation of flash, basic, ajax uploader etc but no joy.

I tried to have images posted as thumbnails and then got this error when rebuilding index :

Warning: Declaration of vB_Image_Magick::fetch_image_info() should be compatible with that of vB_Image_Abstract::fetch_image_info() in ..../includes/class_image.php on line 1256

I saw in another thread to add a line to stop errors to the config file but that didn't work.

Any info appreciated

Error log when trying to upload picture in forum shows :
