I think you are probably trying to call something into your page list that doesn't exist, like an attribute that hasn't been applied/used on one or more of the pages that are in the list.

Hi,
yes I think too,
but how can I come into my page to remove the block which caused the error ?

gr. stefan.

Are you working on code for a custom template for the plugin? If so you could correct the error or remove/rename your template so it defaults back to the default page list view file.

Or you could go directly to your dashboard and disable the block.

Hi
I am working not with codes , just on the front.
Where can I disable the block on that specific page ?

I *think* you can only remove blocks from the site in general via the dashboard.

If you are only using default C5 blocks and views then this is an odd error.

Can you run through the steps you took before the error or what settings you choose when adding the block.

Have you tried changing the theme to the default C5 theme and seeing if the error persists. If it clears then it could be an error in your theme code.

hi
mmhhhhh in this way I have too much risks of lossing setting etc etc
perhaps moving the childpages to another place and remove that page and make a new one
I will ask around if I can approach my page at the back
thanks

You shouldn't lose any settings by changing theme. The only thing is that you won't see any areas not named in the other theme. But when you switch back they should come back as they will still be in the database.

To be sure you can always backup the database before hand.
