PHP-Warning in forums

[heredoc]

I did see an PHP-Warning in the forum while submitting a post:

Warning: Declaration of vB_DataManager_ThreadRate_Multiple::fetch_query() should be compatible with that of vB_DataManager_Multiple::fetch_query() in ..../includes/class_dm_threadrate.php on line 0

I didn't bother to say anything about it yet but,

Clicking on "advanced search" I get
