This is a simple idea from a simple man.
If you have not modified this .tpl and you have not upgraded x-cart, why not restore the version in skin1original dir?
Have you compared either your local copy or the live file to the skin1original tpl?
When I have problems, I just take the distribution archive for the version I am running and extract the problem file and re-upload it. That way I know it is
1. compatible with my current version
2. mint
3. as X-Cart intended it.
Remember to backup before you do anything. Oh yeah, make sure that your upload is ASCII. That may help prevent corruption.
