[Plugin: Types – Custom Fields and Custom Post Types Management] Created Custom Post, does not show

Doesn’t show where?

excuse me: does not show in admin menu

Try 20 (the default) and see if it shows

nope

(and no other plugins active)

You might be right. Please go to Settings->Permalinks and just resave them. I found some cases where the WordPress rewrite rules cache gets changed and causes this.

Resaving the permalinks fixes the problem. We’re investigating now in which cases it happens and going to prevent it.
