I am building a drupal 7 site.
Lately I made a lot of changes and install many modules.
Currently, when I enter into a view, everything looks fine. but, when I enter a field settings inside a view, I see that some of the option are not available - meaning the collapsible option is not available.
I tried to replace the views folder on my server with a folder I backed-up 4 days ago. ran cron, flushed all caches, ran upadte.php - nothing helped.
- Can someone please help me solve this issue?
Here is a screen-shot (you can see they are not clickable and not collapsible):
