Latest Updates caused error in com_easyblog/helpers/helper.php

Since the last Update to JomSocial 3.2.1.4 there are some issues with SH404SEF, EasyDiscuss and EasyBlog again. Something changed. EasyDiscuss posted in JomSocial Stream, but the Links did not work to reach the discussion.
In the Module with latest Blogs error had been displayed.

Warning: Invalid argument supplied for foreach() in /www/htdocs/v121336/mcffa/components/com_easyblog/helpers/helper.php on line 4510

I deactivated sh404sef, cleared the caches. The errors with EasyDiscuss Links in the stream still exist.
In the EasyBlog component I Got the following (3 times):
Warning: Invalid argument supplied for foreach() in /www/htdocs/v121336/mcffa/components/com_easyblog/helpers/helper.php on line 4510

and no blogs are shown. Latest Blog Module shows the same.

So what shall I do?

4510 of helper.php

foreach($groupIds as $key => $val)

We are working/developing on a social website: http://mcffa.ug for "Micro Crowdfunding in Africa", helping e.g. children to go to school and will be able to pay their school fees or get their fees to pay for the university. And some other projects on that website for people who want to work but need help to make their way. So we really need help in any way we can get.
