First of all I want to thank the whole Silverstripe staff and its community for what it is.
Currently I'm undergoing some problems on the newsletter feature in SS. Before I started I did check out the documentation on creating and configuring a newsletter template within SS. But the problem is that my template doesn't show up in the dropdown box when creating a new newsletter. I've tried both ways (mysite/templates/email/ and themes/mytemplate/templates/email/) and also set the extra _config.php lines.
I just can't figure out whats going on and I would really appreciate some help on this one.
I'm using SS 2.3.1, the newsletter module is v0.1.1 and I tried creating a template in various places, including mysite\templates\email as suggested in the documentation. I also added Email::setAdminEmail("[email protected]") to the _config.php file.
The newsletter module is extracted to the root directory for the site, which would be either c:\xampplite\htdocs\directory\... or http://localhost/directory. I think the path is OK because I do get the extra tab in the CMS, and the buttons.
I've also downloaded the user forms module (v0.1.0) but nothing ever happens.
I did have a similar issue to what you described where the buttons where unresponsive but I *think* this was related to the directory name of the module not being set to newsletter. I did change other things at the time and I cannot be sure that this was the solution.
