I have a shared Go Daddy site setup with PHP 5. I am running the site using Rocketheme Hivemind. In Legacy Mode i get the following error with 1.X version of SigPro installed:

Warning: include_once() [function.include]: Failed opening '/home/content/xxxxx/html/mambots/content/plugin_jw_sigpro/sigpro_engine.php' for inclusion (include_path='.:/usr/local/php5/lib/php') in /home/content/xxxxxx/html/plugins/content/plugin_jw_sigpro.php on line 71

When I try the 1.5 version which would be preferred I get the following:

Warning: getimagesize(/home/content/xxxxx/html/images/stories/louisemckinney/dsc_1066.jpg) [function.getimagesize]: failed to open stream: No such file or directory in /home/content/xxxxxxx/html/plugins/content/jwsigpro/sigpro_engine.php on line 86
Image type not supported

I have checked jpg files and they are fine. 

GD Version:
["GD Version"]=>
  string(27) "bundled (2.0.28 compatible)"

I also downloaded both versions today (Feb 18th) uninstalled and tried both 1.X and 1.5.

Hi my friend!

Well... as the server's message say, it can't find the image...
The name of the image are exactly the same, viewed in the error message?
Could be there Uppercase characters?

Take a look at this post , could be helpful!

Also a direct link to the gallery could be helpful too!  :)

Thank you!
