Block not appearing for anonymous users

This only seems to happen with OG 2.8. My sites on 2.7 do not have this issue and rolling back to 2.7 solved the problem on the affected ones.

However, testing on a clean site on simpletest.me does not have this issue so it's still a combination of things causing the problem.

I'd be happy to test it again whenever you get a chance to look. I'll just stay with OG 2.7 for now.

Now that OG has a security update to 2.9, I'm concerned about not being able to update. Granted, the security update doesn't really affect my setup but the warning that I'm missing a security update drives me nuts!

The OG Menu: single and OG menu: double blocks do not appear for anonymous users but both appear fine for authenticated users. It appears that og_context returns nothing for anonymous users.

og_context has changed so that it now has 4 parameters

/**
 * Get or set group context using the menu system.
 *
 * @param $group_type
 *   The context to get by group type. Defaults to "node".
 * @param $group
 *   Optional; The group entity to set as the context.
 * @param $account
 *   Optional; The user entity we are getting context for. If empty, defaults
 *   to current user.
 * @param bool $check_access
 *   Determines if access to the group should be done. Defaults to TRUE.

If I set line 235 of og_menu.module to be

$context = og_context('node',NULL,NULL,FALSE);

Then the og_menus reappear on my pages, however they don't show up on views where I've set a php header that defines the context. When I dpm the og_context function it seems that something else is calling it and removing the context for that views page but I haven't backtraced it yet.

I could create a patch for this but this doesn't seem like a great solution.

Indeed, I didn't suggest that it would be the correct solution. It does speak to the fact that access checks are causing the disappearance though.

Field permissions is enabled but there are no permissions set on the og ref or og_content fields.
Context handling is configured for node, comment, and URL (content create)
OG access is enabled. I disabled it but it did not fix the problem.

I appreciate the suggestions. I'll try disabling other modules and see if I can find more and post it here.

Content access was to blame. We had it setup to not allow the group content types to be seen by anonymous users. (We override the group page using Panels and make it into a dashboard for managing group content). However, I can see how you can't determine context when you don't have access to the content that the og_ref field points to... We'll have to rethink how we do this.

Thanks for taking the time to look at it.

FYI for anyone else who comes looking for this. I can't think of a problem with turning off access check for og_context here. It is just running on hook_block_view and I want anonymous users to view the menu but NOT the group node itself. So I changed line 248:
from

$context = og_context();

to

$context = og_context('node',NULL,NULL,FALSE);
