Fixed [E_WARNING] Invalid argument supplied for foreach()


Active member
Been getting this error a couple times a day the last two days always on the same threads. Says user unknown so can't follow up to find out what the repro was.

Stack trace

Request state
array(4) {
["url"] => string(77) "/forum/threads/threadname.1234/"
["referrer"] => bool(false)
["_GET"] => array(0) {
["_POST"] => array(0) {

Any ideas what might be causing this?

This appears to not be a MG Exception, it's just getting caught by MG. If you search this same error on the entire forum, you'll find it in relation to several add-on errors as well, so seems to just be an exception handler that is catching some downstream exceptions (not sure if that is by design/desirable/avoidable).

In my case, I manually restored some threads and was missing the xf_thread_redirect table entries for these threads. Restored those and no longer getting these errors.

It should be easy to prevent this from triggering though -- we need to check whether the reply has the data we need.

Thus, moving to bugs.
