I have a weird problem and was hoping maybe someone on this community experienced it before or would know a better way to debug the issue.
I help manage a large group of multi-sites in Drupal 7.52. There are currently 9 websites and thousands of nodes, so its not a tiny system. we have 13 roles (including the basic - 6 are custom).
Two of these roles are checked to see "View Interactive Information Bar". Description of this permission is "Allow users to view the IIB. This may allow users to perform administrative tasks.".
There are a bunch more but I will use the above as the example to the issue. We will go say 2-3 weeks with no issues and then all of a sudden this permission will become un-checked ONLY for our custom roles. This applies to a bunch of other permissions as well, what is odd is its not ALL the permissions. It is only a few and they keep repeating, the above permission is one.
I will go in and check it back on, it will be fine for a day and then boom, unchecked again. I will repeat this for maybe 2-3 days and then it will be fine for weeks.
I've checked the logs, error logs etc... and nothing is coming up. I've tried checking CRON to see if it happens when CRON runs but nothing. It almost seems random.
Has anyone ever come across this before? Or know of a way to possibly debug this?
