Blog title and title image rendering issues

Hi,

I currently have an issue where individual blog posts have the following displayed at the top of each post:
D ), 'large', false ); $categories = get_the_category(); if ( ! empty( $categories ) ) { $cat_name = esc_html( $categories[0]->name ); } global $post ?>

and where the image is supposed to be displayed I get:
ID);?>
term_id ) ) . '">' . esc_html( $categories[0]->name ) . ''; ?>

The site has recently been moved to dedicated wordpress hosting so I have been in touch with the hosting company. They haven't been able to find anything that has gone wrong in the move but the suggest the problem might be related to the following files:

JDuploads/content.xml
JDuploads/content-1.xml

They don't suggest what might be wrong, however the naming of these files rings in bell in my head in that I have carried out a resizing of al the images on my site to improve performance which involved a lot of image reloading. Could I have broken something in these files from my upload actions?

Also all plugins have been deactivated to see if they were the cause but proved not to be.

This problem only affects the individual blog posts (all of them) as detailed above and which you can see from the link provided by clicking on any post.

I would be grateful for any assistance you can give to figure this out

Thanks
Richard
