Also having template issues....need to know where to look

Hi all.

I posted this on general questions before I knew there was this override specific forum.

I have a rather serious template problem which is stopping me using any templates other than my own one called 'custom' (Original Eh?)

I can make a template no problem, and it works fine up until displaying an individual product. Then the generated HTML for the page gets this far:

...and then it stops.

This is also true for the classic template. That doesn't work either.

I need a pointer as to what I might have changed to make this error.

My site is https://www.wheredidyougetit.co.uk/shop but I need to leave it in 'working mode' so you won't see the problem.

So a mystery, which I'd love a solution to.

Many thanks in advance to anyone who can help.

When I looked - your site displays an indivual product just fine??

I am looking with FireFox

Additional info looks good in IE also

"My site is https://www.wheredidyougetit.co.uk/shop but I need to leave it in 'working mode' so you won't see the problem."

I need to leave it working as it's in use. I was after a pointer as to what actually happens when a template is selected and the kind of thing that is causing the HTML to stop being generated as specified.

Thanks for answering though, I always appreciate anyone trying to help.

This is also true for the classic template. That doesn't work either.
When you stated this, It should be broken for all templates???

Unless you have made edits to your classic template files also and might not recall?
