I've installed the contrib and got to the backend where I was able to press the sql install button to set up the db, but I was immediately re-directed to the login page. i manually put in the variables and got it to work but when I tried add a related product it did it again!
I'm also getting this error in the front end
Warning: main(includes/modules/FILENAME_RELATED_PRODUCTS) [function.main]: failed to open stream: No such file or directory in /home/content/x/x/x/xxxx/html/product_info.php on line 227
Warning: main() [function.include]: Failed opening 'includes/modules/FILENAME_RELATED_PRODUCTS' for inclusion (include_path='.:/usr/local/lib/php') in /home/content/x/x/x/xxxxxx/html/product_info.php on line 227
Looking forward to getting this working, looks good!
