I have found an odd problem.
The subscription options appear when I first open the profile page on log in both as part of the mod_cbsubscriptions module and as part of the subscriptions tab or in the index.php?option=com_comprofiler&task=pluginclass&plugin=cbpaidsubscriptions&do=displayplans view.
However if I refresh the page or return to it from another page they disappear. The current subscription part of the module and form are still there but the upgrade options are gone. I have attached screenshots (with stuff blanked out). I compared the source before and after refresh and the relevant scripts and forms get removed.
I am pretty sure it was working previously but is not now with CBSubs 2.0.1 (plus CB 1.
or 2.0.2 which I have just upgraded to.
