Manual testing fixed the issue. Patch looks fine.

Still getting this error even with this patch installed. Whenever I try to configure blocks. Wasn't happening in Alpha 3. Only in Alpha 4.

Hm. That sounds like a needs work? Or at least a needs review?

The patch looks pretty sane to me, though.

I'm running a very fresh (today) install of alpha 4 - was getting this error and tried the patch (on the statistics module, not the block module) and it cleared it right up. No errors anymore.

The code in the patch is valid. If there is still a problem, it ought to be an additional problem. Therefore, I decided to commit this patch to CVS HEAD. Thanks.

It looks like this warning is back again. Drupal 7.9 after installing modules.

can you tell the full error message? I would like to know the line number, as there are more foreach loops in _block_rehash().

if it is the same error, then running the attached file will tell you which module has a wrong hook_block_info() implementation.
- rename the file to test.php, copy it into the Drupal root folder and open it in the browser (mysite.com/test.php)

I got this same error message on Drupal 7.7 every time I install new modules.
Warning: Invalid argument supplied for foreach() in _block_rehash() (line 385 of /mysite/modules/block/block.module)

I also had this error: "Warning: Invalid argument supplied for foreach() in _block_rehash() (line 385 of /mysite/modules/block/block.module)"

#10 help me find the culprit. Thanks.

Be great to get this fixed, I also have the same issue:

Warning: Invalid argument supplied for foreach() in _block_rehash() (line 385 of /public_html/modules/block/block.module).

When i tested where the error was coming from it says its the Linkedin module...

I just installed the linkedin module on a clean Drupal 7 install and got:

Warning: Invalid argument supplied for foreach() in _block_rehash() (line 389 of /drupal/htdocs/modules/block/block.module).

If you have the LinkedIn module used on your site, then here is your issue: #1371500: hook_block_info() must return an array() - warns "Invalid argument supplied for foreach() in _block_rehash()"

Thanks Pasqualle!!
I had a custom module not returning anything in hook_block_info() and so I was getting the warning.

This isn't a core issue but a contrib issue. Resetting correct status.
