Hello,

Here is some info about the Lost connection error with MySQL.
stackoverflow.com/questions/10563619/err...-server-during-query

To make it quick the query is too long for your MySQL server. Try to apply the fix mentioned in Stackoverflow or reduce the data in the query.

I think there is not problem with long time query.
This error appear then I wait about two minutes and then refresh page.
May be problem in extension or CB code.

No, not CB, the problem comes from the plugin building a too long query for your server.
The plugin will pick your plugin parameters to build a query to pick in the Sobipro tables.

The more fields you set in the plugin settings the longer the query gets.
But this is the first time I see this so I gess you set quite a few fields.

I'll need to go to your site to solve the quote backslash in title

I send connections in your email.

Thank you, received, can you point me to the url of the user profile with backslash on doublequote issue ?
