TOPIC: [SOLVED] Error when booking

I'm getting an error on http://www.*****.co.uk/open-course-list?controller=event&task=viewCart

It's producing the below:

Table not found

Can anyone advise?

You need to update DT Register to the latest package. Your issue is that OR you have already updated but you have old elements in place still. You have template overrides in place for DT Register and you MUST replace them with updated versions. Get the latest files and re-apply your customizations to them. Also make sure you have all DT Reg modules and plugins updated, including CB or JomSocial plugins.

In your case, this is definitely a template overrides issue.

Hi,

I just downloaded and ran DTRegister3_2_7_PKG_J3x - it's still doing exactly the same thing

Yes, but read my full reply above. You have OLD template overrides in place. Our announcements for the last couple of updates stated that any existing template overrides would have to be updated as well.

I did read your full reply, and I'm afraid I don't understand what you are saying. I'm not aware of having any template overrides in place - if I do, how do I find them, and how to I overwrite them?

You have at least one template override as it is referenced in the error code you posted:

#0 DtrTable::getInstance(event, Table) called at [/var/sites/g/**********.co.uk/public_html/templates/uGDR/html/com_dtregister/event/viewcart.php:25]

Any files that you have loaded into /templates/uGDR/html/com_dtregister/ are tmpl files that you have modified. Those will load IN PLACE OF updated files in the main components directory. They reference an old DT Register file that no longer exists... among other changes that were brought on by recent Joomla updates.

Whatever files are there, you'll need to grab the updated versions of those files. Either unzip the component install package to find them or grab them from /components/com_dtregister/views/. Re-apply any needed customizations and then replace your existing override files with the newer versions of them.
