We upgraded Modx some weeks ago using UpgradeModx and have been gradually tracking down bugs. One or two persist, but they have the effect of taking out bits of the manager - maybe the Snippets won't load or the Template Variables in the Element Tree, for example. Sometimes the whole manager shows Error 500. In all cases, using SSH to ensure core/cache is totally empty sorts the problem - temporarily. It wouldn't be a huge issue but various snippets stop working which logged-in front end users need, so it's a pain.
We see two errors thrown, one is Smarty related the other Extended Fields. I suspect the Smarty one is the culprit but don't understand enough.
We see

if (!file_put_contents($_tmp_file, $_contents)) {
error_reporting($_error_reporting);
throw new SmartyException("unable to write file {$_tmp_file}");
The extended profiles error is
[Mon Apr 10 05:59:32 2017] [warn] [client xx.xx.xx.xx] mod_fcgid: stderr: PHP Fatal error: Call to a member function get() on a non-object in /home/g/public_html/core/cache/includes/elements/modsnippet/91.include.cache.php on line 8
with lines 7 & 8 being
$profile = $modx->user->getOne('Profile');
$extended = $profile->get('extended');
Any help appreciated.
