Hello, I'm relatively new to osc and need some help with this add-on. I used all the files as-is and got everything working, except for 2 problems: 1.) I had previous/next buttons so customers could go from one product to the next without backing up to the category main page, and those disappeared. 2.) I can no longer access my catalog to edit products. The error I got when I used the exact file from the download was Fatal error: Call to undefined function: tep_hide_session_id() in D:\inetpub\wapellocounty.org\httpdocs\americangothic\sales\admin\categories.php on line 908 I then edited my original categories file with the commented add-on code, and got this error: Parse error: syntax error, unexpected '}' in D:\inetpub\wapellocounty.org\httpdocs\americangothic\sales\admin\categories.php on line 683 No idea what either of these means or how to fix them. When I got the second error I compared the file with the previous version and found no difference near line 683. Can anyone help with this?
