Problem/Motivation

When installing AddThis 7.x-4.0-alpha4 on a clean setup, with no AddThis installed before, the AddThis block give a (White Screen of Dead) WSOD. Other versions before alpha5 might have this problem too.

The Apache error.log returns.

PHP Fatal error:  Unsupported operand types in /sites/all/modules/addthis/addthis.module on line 257, referer: http://example.com/admin/structure/block
PHP Stack trace:, referer: http://example.com/admin/structure/block

PHP   9. _addthis_settings_form() /sites/all/modules/addthis/includes/addthis.block.inc:103, referer: http://example.com/admin/structure/block

Basicly the value that was beeing set is not a array so the + operator at that line is incorrect.
This issue is fixed in #2181367: Error Fatal error: Unsupported operand types and release in 7.x-4.0-alpha5.

Original post

I installed the module and enabled the block and when I clicked the "configure" link on the admin/structure/block page I ended up with a blank page. I checked my logs and no errors were logged by Drupal or Apache.

I expected to see whatever configuration options are available for the block. I'm not sure what those options are, since the page never rendered.

I can confirm this is happening to me as well.

Do you have field ui enabled. The vonfig uses functions that are in there.

Yes and confirmed.

I'm seeing this problem as well, with addthis-7.x-4.0-alpha4. I cannot configure the block, and so it doesn't show up because I can't add any services to it.

In the log, i get this error:

Message The following module is missing from the file system: .

Which is mysterious, because whatever module is missing doesn't seem to be there.

I'm running this on Ubercart, but otherwise I don't think I have any modules that would interfere.

I have had this problem both with and without installing display_suite.

I tried to work around this by using "drush vset" to manually set the variables to make the block show up, but I'm not sure I can do that on the commandline because of all the newlines and returns involved.

And do you all have the submodule AddThis Displays installed?

I'm getting an error when I try to configure AddThis as a block assigned to a region. I get the error:

Fatal error: Unsupported operand types in ...URL.../addthis/addthis.module on line 257

Also, the AddThis module sais it is supposed to be able to configure permissions. However, there exists no entry for AddThis in the permissions page after installation and enabling the module.

Greetings!

  • P.S.: This happens regardless of having "AddThis Displays" enabled or not.

I also experience this problem: ending up with a blank page when clicking on configure link on the admin/structure/block page. I have AddThis Displays installed and enabled and also field ui.

Change this on line 257 in addthis.module
$settings += $formatter_settings;
to this
$settings[] = $formatter_settings;

This should fix the issue.

@krishnair

Very nice debug. Both the issues of

  • not being able to view/edit AddThis's permissions,
  • as well as not being able to assign AddThis as a block to a region

are fixed by your modification in comment #12.

Thanks,
V.

I confirm that the fix provided in comment #12 works good.
I think this should be committed as soon as possible.

Best regards

Please try to update to the latest 7.x-4.0-alpha5 to see if the problem is still there.

I'm seeing this with alpha6. The fix in comment #12 seems to have worked nicely.
