Caching Phrase Groups

[futureal]

I am running into an odd phrase-related problem that I can't quite nail down. I've created a new group of phrases, and I want to pre-cache them for a Control Panel page.

Thus, I have changed the $phrasegroups section of the file from this:

// #################### PRE-CACHE TEMPLATES AND DATA ######################
$phrasegroups = array('cpuser');

To this:

// #################### PRE-CACHE TEMPLATES AND DATA ######################
$phrasegroups = array('mygroup', 'cpuser');

However, once that has been done, if I go back and attempt to access that page, it produces the following SQL error:

Database error in vBulletin 3.0.7:
Invalid SQL: 
				SELECT * FROM cpsession
				WHERE userid = 
						AND hash = '83e75790aa132d737560766ce115cbc2'
						AND dateline > 1119849369
mysql error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND hash = '83e75790aa132d737560766ce115cbc2'
						AND dateline > 
mysql error number: 1064

I can't for the life of me figure out what is causing that. I've traced things back in global.php but I'm obviously missing something. Any ideas?
