I had recommend running on a previous install of Joomla 1.5 and it all worked great.

I recently installed a fresh version of Joomla 1.5 on my new server and uploaded Recommend to it, set all the settings exactly the same, and now I get a Error 500 Internal Server Error message after clicking the "submit" button.

I don't know if I am forgetting to install something in the new server or what. I have Legacy 1.0 turned on because some other plugins/modules I use require it and all of my server settings for sendmail are exactly the same as before. The only thing I did was change the server machine within my own home network and I installed everything fresh from scratch.

Any ideas on maybe something I missed or have not installed yet that will help this run? I have been through the old server and new server configs repeatedly.

Another thing I might point out is that I am using Linux and I may not have a required library or program installed on it that I did on the previous server, maybe a php library or something?

Any and all help is much appreciated. All other mail functions for Joomla work, just not for Recommend.
