[patch] Unable to see link "Ticket Template"

You can check if simplejson is installed first. If yes, look up at trac's log file can get more information.

me too

This is related to assigning a wrong permission.

I've found this issue with 0.6 and it continued when upgrading to 0.7 once more today. So I just went on to get it fixed. Following small patch provides the intended behavior - show the admin page with 'Ticket Template' view for any user with TT_ADMIN permission, (or another admin page and a 'Ticket Template' link, if user has more admin permissions):

     # IAdminPanelProvider methods
     def get_admin_panels(self, req):
-        if 'TT_ADMIN' in req.perm:
+        if 'TRAC_ADMIN' in req.perm:
             yield ('ticket', _('Ticket System'), 'tickettemplate', _('Ticket Template'))
 
     def render_admin_panel(self, req, cat, page, path_info):

Again, this should really be fixed at least for TracTicketTemplatePlugin 0.6 and 0.7, since these versions are know to be affected in a way, that the TT_ADMIN permission is rendered useless and only users with TRAC_ADMIN (that implicitly collects all permission anyway) are able to access the admin page.

pushing this a bit more

Uh, very sorry, the previous patch is actually just the other way around:

See #8609 for a follow-up on permissions, that proposes an second permission to better control the "my templates" selection instead of just 'all-or-nothing'.

(In [9956]) Fixed #8609 , add permission TT_USER to fine grained control user custom templates

As mentioned there, this should fix the original problem here as well. Anyone having still problems should re-open this ticket.
