warning: call_user_func_array() First argument is expected to be a valid callback, 'theme_imagecache_formatter' was given in

I just upgraded to the newest version and I'm having the same issues.

I encountered the same notices after an upgrade from 6.x-2.0-beta8 to 6.x-2.0-beta10.

The notices kept appearing on all the pages (admin and public visitors) of my testsite... however after a few (about 10 or so) page views the notices disappeared.

I noticed several other topics (other modules), like #246247: warning: call_user_func_array() after upgrade... so I assume it's not an Imagecache related issue only.

I didn't changed the version number of this queue, because it first seemed to appear in beta9, but it applies for beta10 also.

Best,

hi all, I know this will sound petty, I had this issue when I upgraded the Imagecache module. I ran update.php and it solved it.

I hope this will help

#3 is correct, but if your site cache is enabled, you also have to clear it.

This error seems to have appeared after upgrading to 6.x-2.0-beta10, so I changed the version for this issue as well.

Thanks again for the great module.

Sorry, I somehow missed VinceW's comment about it appearing in beta9 as well, so I'm changing the version back. Cheers.

#3 + #4 worked fine for me. So probably this is not a bug really but a matter of proper update handling by site admin.

This definitely appears to be a bug. Problem is intermittent but causes images to disappear from the site. Also seems to affect the loading of other modules and / or page scripts / css files - I'm basing this on the fact that several CSS rules seem to be ignored (unloaded) when the error occurs. Clearing the cache or running update.php fixes the issue temporarily. I haven't been able to figure out what triggers this error, but all of a sudden I start seeing reams of errors in my log looking like this:

call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'theme_imagecache_formatter' was given in /home/wuh/public_html/serein.co.uk/includes/theme.inc on line 617.

This happened again on my site last night and I was able to perform a little more debugging. I have narrowed down the cause to a record in the cache table. The record looks like this:

cid: theme_registry:mytheme
data: [BLOB - 141.5 KiB]
expire: 0
created: 1254434395
serialized: 1

If I delete it, my images return and the theme_imagecache_formatter errors stop appearing. If I re-insert the exact same record, the problems reappear.

Could this bug / issue be related to this? - http://drupal.org/node/496198

In dire need of help

Seems like clearing the cache sometimes helps this problem go away.

I also suspect it maybe a permissions issue relating to imagecache.

No images where shown for me either, but I just cleared the cache as #4 said and worked like a charm!

Thanks for the help!!!

Please reopen if this is still an issue with ImageCache 6.x-2.0-rc1.
