Qurl on "[Plugin: Dynamic Widgets] Mysql strict mode error"

I'm sorry. MySQL strict mode ensures MySQL does not truncate or otherwise modify data to conform to an underlying data type, when an incompatible value is inserted into that type.

Because of the dynamic nature of Dynamic Widgets and the way it's programmed it can -as you already noticed- insert a different data type or perform a tuncation in the database table.

One thing you could try is changing the name column in de dynamic_widgets table to allow a NULL value and default to NULL:
ALTER TABLE [prefix]dynamic_widgets CHANGE name name VARCHAR( 40 ) NULL DEFAULT NULL
