warning: unserialize() expects parameter 1 to be string [#303101]

warning: unserialize() expects parameter 1 to be string, array given in /opt/lampp/htdocs/asokhoah/sites/all/modules/lightbox2/lightbox2.formatter.inc on line 138.

Using imagefield 6.x-3.0-alpha2 in nodes, I'm getting one of those for each imagefield image in the node.

Similar issue with this on imagecache btw, with an interesting discussion: http://drupal.org/node/299329 , wich led me to try out the following:

replaced:
$image_data = unserialize($item['data']);
with this:

  if (is_string($item['data'])) {
  $image_data = unserialize($item['data']);
 }

Which does get rid of the error, but if you use the titles don't get passed as captions... not a developer myself though.

If you have it setup to display the link to the node as caption, the html is printed out as plain text also. Maybe this gives u a clue?

Fixed in CVS and will be included in the next dev release, available later today.

I think the problem with your change is that $image_data is not set if $item['data'] isn't a string. See if the next dev version or the attached patch fixes this for you.

Cheers,
Stella

I added the line drupal_set_message(dprint_r($item['data'], 1));

above the unserialize() function call, and this is what gets printed:
