FC 3.1.0-rc2 - Post Installation issue

I hope that this is the correct forum in which to post this:

I've just installed the latest FC 3.1.0-rc2 and am using the following:

Joomla 3.6.2
PHP 7.0.11
mySQL 5.5.52

After installing, FC, I get the following error on the page showing "Post Installation" messages:

Warning: Invalid argument supplied for foreach() in /home/www/html/subs/travel/en/administrator/components/com_flexicontent/models/flexicontent.php on line 2299

The "initial permission" lines shows a "-" (negative) mark with "update" next to it. If I click on the "update" option the negative mark changes to a checkmark to show that the update is complete. I refresh the page and the warning line shown above is still there and the "initial permission" option has changed back to negative.

Any ideas?

Thanks. -- Rik

Hello

There were some changes and a fix for a rare issue regarding "Initial permission creation", this was done after v3.1.0-rc2a
and it may be your case

Is this a developing web-site or a live one ?
- if this is a new web-site / developing, please click
"Clone or download" / "download zip"
from here and install it via Joomla extension manager
github.com/FLEXIcontent/flexicontent-cck/tree/3.1.x-stable

otherwise you may send me aPM with super admin access

Thank you for the suggestion.

The newer rc3 version seems to have fixed the problem (after also clearing my browser cache).

Thank you very much! -- Rik
