Problem Yommy's plugin "VEND_SQL", crash server with it

[Daraen 7]

Hi, Yommy If you go by, can you tell me why I get a server crash after activating your plugins when I enter the @autotrade command.

 

I would like to use this add on for cp feed developed exclusively in relation to this plugin because hercules does not offer anything to display merchants / buyingstores.

The only error that pops up on my server is:
 

$ [Error]: Server received crash signal! Attempting to save all online characters!

I have no idea where the error occurs, the only direction I have is that it comes after an @autotrade.
I specify that my @autotrade works perfectly when I deactivate this plugin.
I am using a client 2018-04-18b

I will appreciate if someone helps me fix this problem.

Thank you
