Smarty error: unable to read resource: "./opc-product-line.tpl"

[need4speed]

I have tried to add a custom hook to my database but I reset it again so that shouldnt have caused the problem.

But now im having this smart error I really hope somebody can help me fix it.

Warning: Smarty error: unable to read resource: "./opc-product-line.tpl" in /var/www/vhosts/xxxx.com/httpdocs/tools/smarty/Smarty.class.php on line 1095

The problem only shows in Firefox not in IE8 or Chrome.

it seems the file opc-product-line.tpl is missing from your themes/[your_theme]/ folder or from one of your install modules

do you have one page checkout module installed? what prestashop version do you use?

[need4speed]

It is a module.

Im using 1.3.1 It might only be a session problem sence my friend is not getting the error and he tested with Firefox as well.

[Radu]

it doesn't seem a session problem - maybe you are doing something else than your friend - the file is not a standard 1.3.1 file

[need4speed]

I mean its a module but not a standard module in Prestashop.

Its the Onepagecheckout module I have purchased and installed.

[Radu]

exactly - if you don't use it just uninstall it, if you do use it and you are still getting errors ask also the developer, he has a better experience and maybe run accross the same problem. but it doesn't seem a session problem in my opinion

try to uninstall the module and reinstall it again.
