Warning: array_flip() entity.inc

*what* enabled modules?

This usually indicates that a module is calling user_load() in a wrong way, for example user_load(array('uid' => 1)), which is not supported anymore in D7.

Try to either disable each of those modules one by one and see if the error still happens once you figure out which module is responsible.

Then move this issue to the issue queue of that module

You can also search for "user_load(array" in sites/all/modules, might be faster if you have a tool that can search recursive through directories.

Moving the issue.

Line 29 and 34 of path_title/modules/user.page_title.inc is causing this

It calls "user_load" with an array as the first parameter instead of just the uid

Line 29:

Currently: $types['user'] = user_load(array('uid' => arg(1)));
Should be: $types['user'] = user_load(arg(1));

Line 34:

Currently:  $types['user'] = user_load(array('uid' => arg(1)));
Should be: $types['user'] = user_load(arg(1));

Actually, can we not optimise this code and first check if a pattern was defined for the user (a variable get is much faster than a user_load), so the idea is that we only set "$types" if "$pattern != empty string". I'm asking because I'm not sure how "$types" is used in the rest of the code.

PS: Sorry I don't have my "patching enviroment" set up at the moment - moved to a new pc. Will submit a patch soon so that this can work with drush make's patching system.

Patch attached :)

I also see there are tests for taxonomy and all sorts of things, but not a test for the user page. Once I've gone through a few "how to write simpletests for drupal" tutorials I'll try to tackle that as well.

Haven't tested it, but the patch is correct and simple.

@nightowl77 patch works, thanks for the quick fix!

May I ask when this patch will find its way into the 'Page Title' module? The current versions (2010-Nov-02) of it are quite old. In addition to that, other Drupalistas seem to suffer from this bug as well, see #1019936: Problem with array_flip() .

Thanks for the module! It is great.

The patch worked thanks.

Thanks guys - committed to dev. Will be in the next main release.

I am very new to Drupal.. how do I apply this patch?

@spunge: Instead of applying the patch, you are well advised to take the most current dev version of this module!

Ok. Do I remove the current version of the module first or do I just overwrite and replace it with the current dev version?

... replace it -- unless the instructions are otherwise (usually when there is no upgrade path).
