CF v3 - Plugins disappear from Plugins Tab when enabled

For some reason, when I enable a plugin in the Plugins tab, it disappears. If I go back in and click another one, when I go back in, the new one will be gone, but the old one will show up... although not enabled. Is there a common fix for this?

Thank you for your time.

The installation of ChronoForms on this site is validated. (if that makes a difference)

Hi ChiefGoFor,

I've never seen that before, can only guess that there is something odd with the JavaScript.

By all means email or PM me the site URL and a SuperAdmin login and I'll take a quick look.

PS Validation should make no difference.

Hi Bob,

Problem solved! MooTools upgrade plugin is always getting in the way.

Thank you for your time.🙂
