plexWatch SSL error

I’m getting the following error (in bold) with Pushover in plexWatch:

$ /opt/plexWatch/plexWatch.pl --test_notify=start
Sun Nov  8 22:51:33 2015: DEBUG test_notify: user: title [T or D - for Transcoded or Direct] [year of video] [rating of video - TV-MA, R, PG-13, etc] on client platform [progress of video [only available/correct on --watching and stop events] in] Client IP Address
Failed to post Pushover notification -- title [T or D - for Transcoded or Direct] [year of video] [rating of video - TV-MA, R, PG-13, etc] on client platform [progress of video [only available/correct on --watching and stop events] in] Client IP Address result:SSL_verify_mode must be a number and not a string at /usr/share/perl5/IO/Socket/SSL.pm line 2130.

Specific error, broken out for ease of reading:
result:SSL_verify_mode must be a number and not a string at /usr/share/perl5/IO/Socket/SSL.pm line 2130.

I suspect something changed in the Net::Socket::SSL library. I have a fresh Ubuntu 15.10 server install with the following version of IO::Socket::SSL

 $cpan -D IO::Socket::SSL

From the main PlexWatch thread:

I solved this by deleting this line from plexWatch.pl:
SSL_verify_mode => “SSL_VERIFY_NONE”,

Probably not the most secure way to do it, so do so at your own risk.

SSL_verify_mode => “SSL_VERIFY_NONE”,

should actually be

SSL_verify_mode => SSL_VERIFY_NONE,

as this is a constant, not a string.
