Update time
Again, apologies for delay in following through with suggestions - I've had a relative admitted to hospital a couple of hundred miles away and have been up and down the motorway non-stop. On to better news...

Following knuckle's advice, I renamed
Code:
- /includes/templates/YOUR_TEMPLATE/templates/tpl_login_default.php
- /includes/templates/YOUR_TEMPLATE/templates/tpl_timeout_default.php
as temp files first, and attempted to log in. And guess what? It worked! I tried IE first and got the insecure item warning, so amended the macromedia links in the movie script and tried again - no problem logging in at all. Daring to hope, I tried FF, and was logged straight in again! Thats it, its solved! Unfortunately, as is the way with these things, its flagged up another issue but I'll have run a search on that in the forums before posting another thread if necessary - sigh

But this issue is indeed resolved and my heartfelt thanks to all contributors for their advice in rectifying it. P.S. Linda - the link in your sig to http://www.zen-cart.com/index.php?ma...es&pages_id=14 isn't working correctly somewhere - on clicking the 'one time donate' I get the following message from PayPal
