I have a problem with a JDBC Connection to CSV-Files. I installed the JDBC driver on the server. I created a new system (Driver Class Name: org.relique.jdbc.csv.CsvDriver // Connection URL: jdbc:relique:csv:/"directory"). The connection test in the portal says "Connection successful". But in Visual Composer i get the following error message: "Error -21003Cannot retrieve catalogs and schemas. Database.MetaData.getTablePriviliges(String,String,String,String)unsupported"
