Changes aren't saving after upgrade to 7.10.5

After upgrading to 7.10.5, I’m receiving this error when I try to make changes to a current Project. The edits also aren’t saving.

Warning: property_exists() expects exactly 2 parameters, 1 given in /home3/dwayne/ on line 338

Thanks for the bug report, we’ve fixed it now.

You can apply the simple change manually

The change removes the parameter error, but my Accounts Relate field still isn’t updating when I make changes. Can you assist, please?

It looks like the information already entered on a project is either visible in the list view or in the Display view, but not always both, which seems strange.

Did the warning disappear from the log after you applied the fix?

Maybe you have an additional problem, independent of this one.
