Error in YabbSE admin section, fix it before upgrading to SMF?

[Sheep666]

SMF Version: Version not known
I have below mentioned error in the admin section (YabbSE 1.5.5). Because of this error I cannot put my board in maintenance mode, but everything else seems to work fine.
Think it's really time now to upgrade to SMF, but do I have to fix this first? If yes, someone knows how

Apparently your /yabbse directory needs to be writable to put your forum in maintenancemode.
