Summary:
If curl is present but not curlSSL then we get an ambiguous error.
Detailed Description:
I installed TweetMadeSimple on a server without curl support. Which of course
gave me a nice error as it should.
I then recompiled Apache / PHP with curl support (but not SSL) and got the error
UnsignWe caught an unexpected Exception
which I think is the same problem as reported in the Dutch boards here:
http://forum.cmsmadesimple.org/viewtopic.php?f=13&t=60412
I recompiled Apache with curlSSL support and that solved the problem for me.
We should probably update the check for curl in action.defaultadmin.php so that
it looks for CURL_VERSION_SSL rather than function_exists('curl_init').
http://www.php.net/manual/en/function.curl-version.php
has some details.
Thanks for your work though - nice module.
