? have a problem with Regenerate Thumbnails

I am getting this problem too.

I am getting the identical debugging message.

Total Images: 7
Images Resized: 0
Resize Failures: 7

function () { if (a) { var t = a.length; (function r(t) {v.each(t, function (t, n) {var i = v.type(n);i === “function” ? (!e.unique || !c.has(n)) && a.push(n) : n && n.length && i !== “string” && r(n);});}(arguments), i ? (o = a.length) : n && (s = t, l(n))); } return this; }

This is on a brand new install of 3.5 (having lots of issues with 3.5 already)

With all plugins disabled the message is the same. From the main screen to regenerate all thumbnails or from the media page and attempting to regenerate thumbs for a single message, same problem.

Just for the sake of thoroughness, I tried chmod 0777 on uploads directory, the subdirectories and all image files. Problem persists.

Interestingly, I have a WP 3.4 installation on the same server and the plugin is working fine there.

OK, more information:

It actually IS regenerating the thumbnails!

The file times were updated in FTP, so I suspected this might be what was happening.

I changed the featured image size in my theme’s functions via set_post_thumbnail_size and ran the regenerate all thumbnails again.

Still got the error messages:

However, it successfully created new images in the expected sizes and seems to have regenerated all the existing sizes since the timestamps have been updated on these.

I think I found a solution to this problem, at least for some WP 3.5 users.

As counterintuitive as it sounds, disabling debug mode fixed it for me.

If you are running 3.5 and have WP_DEBUG defined as true in wp-admin, try setting it to false and see if it helps.

This solved several other problems for my 3.5 installation as well, as noted here.
