The bwg_option table ( pastebin.com/HhWxfSm2 ) is constructed in a way that it hits a default hard limit in MySQL 5.5+: dev.mysql.com/doc/refman/5.5/en/column-count-limit.html

Please get rid of this table. This should be either a single wordpress option, where the values are serialized, or each column should be a prefixed option.

There is no need to this table to exist at all.

Hi Peter!

Thank you for letting us know about this problem!

We discussed this issue with our developers, and they confirm, that this table is essential for Slider WD options. However, they appreciate your report regarding this issue, they will take a look at the issue and fix the bug in one of the next couple of updates.

Thanks! Have a wonderful day!
