There is a bug/error in the sqlitemanager.kmm macro in Sqlite Manager extension.

As it was taked from httpmonitor extension, who adapted it left a string and override the Development menu entry for http monitor. Also was removed a parentheses.

Fix:

# K-Meleon Macros (http://kmeleon.sourceforge.net/wiki/index.php?id=MacroLanguage)

# -----

sqlitemanager{
$OpenURL="chrome://sqlitemanager/content/sqlitemanager.xul";
$ExecMacros="OpenURL_InNewWindow"; &ExecMacros_Frames;
}

sqlitemanager_BuildMenu{
setmenu("Development",macro,"SQLite Manager",sqlitemanager);
}

$OnInit=$OnInit."sqlitemanager_BuildMenu;";
# ---------------------------------------------------------------------------
$macroModules=$macroModules."sqlitemanager;";

Before this was left httpkm instead.
