Default Layout file is not exists! Please goto to template manager and create a new layout first.

Hi,

It seems this is not related to Helix Ultimate. I tried to switch to Joomla default template and error is still there..

I'll try to reinstall Joomla core files..

Hi. I faced the same problem. In my case, only HU did not work. Protostar and Beez worked fine. The reason was Advanced Template Manager.

Thanks for this @Pavel this really helped me.

Does this need reported to the developer?

Hi. You are wellcome.

Additional information, for those who face this problem: the problem is not only about the fault of Advanced Template Manager. But in the case before the upgrade you have had multiple template styles linked to different pages. To solve the problem, you need to go to the template's menu binding settings, remove all selections, save, re-select, save. For the default template style - select everything, save, remove the selection, save.

I have the same problem.

The solution is not to update "System - Helix Ultimate Framework" site plugin. For me it stops working when I update from version 1.1.4 to 2.0.2. You can update Joomla core including all extensions to the latest version except this plugin.

If you are updating the Helix Framework, then you need to disable the Advance Template Manager. You can choose what is more important to you, or wait for a new version of the Helix template where they fix it. For me it is Advance Template Manager.

I have the same problem and I do not have the Advanced Template Manager installed.

It is related to Helix Ultimate (current version 2.0.4). Another Template (VMBeez) works. My Shop is called via a menu VirtueMart Category Layout. But Helix expects a SP Page, but there is no such a page. That is why the layout of the page is not found. The message

"Default Layout file is not exists! Please goto to template manager and create a new layout first." refers to the missing page layout; this looks like a Helix Bug.

Hi. If it had a relation to the menu item, you would receive 404 page. So you are mistaken.

Just make a reselection associate menu items in the template settings and save it. Read my post above.

This is not a bug. Just new features appeared, about which the database of your site knows nothing. Therefore, you just need to make reselection, clean the cache and save.

Hope your template is Helix Ultimate Free. Because premium templates based on Helix Ultimate are not ready to update.

Thanks, I will try it. But I don't understand quite well what to reselect.
