open graph update

Looking at that error, it's throwing the error that ' list' is an unknown method instead of the 'list' call (notice the extra space). My guess is that if you copied the code from the forum thread, there may be a strange character or a weird carriage return or something that got copied as well. Can you try to delete all of the white space around the new code that you placed in there or manually type in the code?

I sent you an email with the file. Our forum extension was having trouble attaching the file.

Have you updated to Joomla 3.6.3 on that site already?

We had to do a bit of research. Basically, Joomla 3.6.3 added some additional validation to database columns that were stored as JSON.

We haven't heard of any other users with this error message and we can't recreate it ourselves. What the error means though is that one of the params fields for a user in JFBConnect seems to not pass the validation check that was added in Joomla 3.6.3.

For more details on the full issue, please see this lengthy Joomla.org thread of many other users experiencing this problem in many extensions:
forum.joomla.org/viewtopic.php?t=937036

There was one particular post that described an update to a Joomla core file which would at least print out which field had the issue, which would be very helpful to us if you could implement this and report your findings:
forum.joomla.org/viewtopic.php?t=937036#p3436438

There's also a whole developer thread discussing the problem, but it seems like Joomla is not going to revert the change. Frankly, I'm ok with them not reverting, but do feel the error message could provide a lot more information to help track down issues:
github.com/joomla/joomla-cms/issues/12460

Please let us know if you implement the code above to report which field is having the problem which will greatly help us understand where things are going south.

Thanks,
Alex
