Thumbnails Suddenly Stopped Working

Thanks, I’ll try doing that — BUT all plugins I have now were already in place before the problem began — and there haven’t been any updates in the last couple of days.

The thumbnail problem began this past Tuesday, after a move to a new hosting company. The site is currently on a VPS server at hostgator.com.

So, I’m wondering if it’s some sort of server issue (memory? permissions?) that’s causing this.

I was also wondering if anyone has any idea if this could be server configuration issue.

A couple of WordPress functions stopped working after the move, but once the hosting company increased the memory available for the site, those issues were taken care of.

Any ideas?

That would be MUCH appreciated. This has been a major headache.

esmi,

Thank you for your response. I’ll be contacting the hosting company right away.

Also, if you don’t mind, any ideas regarding my questions a), b), and c)?

Questions a) & b): The featured image *is* being created, but only in full-size mode. Is there a way to force it to create the featured image as a thumbnail? And ONLY as a thumbnail of a SINGLE, specific size?

Question c) relates to something else: Last night I found out that wp-uploads now has three (or four?) copies of each image on the site, in various sizes. Is there a way for me to get rid of ALL those images EXCEPT for the small thumbnails?? (I already have the full-sized images located elsewhere on the site’s root folder.)

Your assistance — and that of anybody else’s — would be MUCH appreciated.

Unfortunately, the problem continues even though I’ve purged the SuperCache/Cloud Flare caches.

Only full-size images are uploaded after they’re “crunched.” No option for choosing other sizes. No option for editing the images.

This is the current code I have in the site’s functions.php:

if ( !function_exists( 'my_theme_support' ) ) :
function my_theme_support() {
  add_theme_support( 'post-thumbnails' );
  add_image_size( 'custom_thumb', 150, 150, true);
}
endif;
add_action( 'after_setup_theme', 'my_theme_support' );

add_filter( 'post_thumbnail_size', 'my_post_image_size' );
function my_post_image_size( $size ) {
	$size = 'custom_thumb';
	return $size;
}

if (function_exists('add_filter'))
add_filter( 'the_excerpt', 'excerpt_thumbnail' );
function excerpt_thumbnail($excerpt){
    if(is_single()) return $excerpt;
    global $post;
    if ( has_post_thumbnail() ) {
        $img .= '<a href="'.get_permalink($post->ID).'">'.get_the_post_thumbnail($post->ID, 'custom_thumb').'</a>';
    } else {
        $img = '';
    }
    return $img.$excerpt;
}

Any other suggestions/possible solutions?
That would be **much** appreciated.

Addendum:

I’ve just tried installing the Auto Generate Thumbnails plugin to see if that’d help. It didn’t.

Instead of generating a thumbnail (150×150 as specified in functions.php), the featured image came out broken. The uploaded image was, once again, a full-sized image.

This is driving me nuts…and it has become a serious problem because I’ve been refraining from uploading new posts with the full-sized thumbnails because they’re dramatically slowing down the homepage (www.altfg.com) and several tag-archive pages.

Also, I’ve noticed that even though I have “functions” set up to crop thumbnails to 150×150, those are being bypassed in the posts with full-sized thumbs. Remember, as I explain in my first post (see above) this issue began after my site was transferred from one hosting company to another this past Tuesday. Before that, everything was working just fine.

Any suggestion on how I can solve this problem?? That’d be ***much*** appreciated.
