Cannot save stuff Style Variable EditorNot sure if this is the correct place to post)

[Rizzie]

Hello!

I'm currently encountering a problem that occurs whenever I try to save a variable in the "Style Variable Editor". This problem occurs everytime.

Here it is:

Warning: Declaration of vB_DataManager_StyleVarDefn::delete() should be compatible with that of vB_DataManager::delete() in ..../includes/class_dm_stylevar.php on line 233

Warning: Declaration of vB_DataManager_StyleVar::save() should be compatible with that of vB_DataManager::save() in ..../includes/functions_log_error.php on line 615

Fatal error: Field username is not defined in $validfields in class vB_DataManager_StyleVarBackground in ..../includes/class_dm.php on line 515

PLEASE help me. If anything is needed, do ask for it.

Thanks!!!
