With the version 2.0.9, the options of block has changed.

then the block with many options or with option with long content don't run, we cannot save options in edit (admin blocks)

I have a block with 19 options, and XOOPS tries save in:
table newblocks
field options varchar(255)

I have changed the type field to text

The blocks with few options have sufficient with varchar(255) if the content of options are not very long
