SMF error

Hi, I have a probelm, sometimes (not ever!) I have this error when I access to the forum, then if I refresh the page I can see the forum (I use the SMF bridge, I don’t now if it is the probelm...)
error:

any ideas? on the smf forum said that is a modx error

This is a very old thread...has this problem been solved since?

For those that might run into this problem, the fix (at least, for us) was to stick SMF and MODx in the same database.

Just to echo "The Man Can", we ran into this problem a few days ago. As also mentioned above, this is a problem has been mentioned in the forums (http://modxcms.com/forums/index.php/topic,3565.msg28817.html#msg28817) for awhile. As "The Man Can" mentioned, when we combined the databases into 1, the problem disappeared. It’s a frustrating problem for sure...not sure why it occurs.
