Just setting up CB Subs on Live site (actually on J 1.5.11)- Off-line Gateway. Put in the Address, bank details etc - Save. On re-opening for edit, it's gone back to installation default values. OK on test site, also on J1.15.11, both CB Subs 1.0.3.

PayPal Gateway details saved OK on both sites.
I notice that at the live site, I am getting HTML editor only as admin although set to use TMEdit

Trying to find if/where Editor is set for CB/CB subs, I tried editing params for plugin BB Paid subscriptions, I got error "The plugin CB Core has no administrator file /home/communit/public_html/components/com_profiler/plug/user/plug_cbcore/admin.cb.core.php" on test site and same but without the full pathname on live site.

Both now upgraded to J 1.5.15; test site still on cb1.2.1 Tiny MCE, live on cb1.2.2, TMEdit default and set for Admin - AHA!! -set editor on live as Tiny MCE, default for admin, now saves - sorry for possibly unnecessary post (still no admin.cb.core.php!)
