Hi Milos 

the original query that was working is:

////////////////////////////////////////////

SELECT ranking_overall as 'Pos Gene', 
       ranking_gender as 'Pos Categ', 
       category as categoria, 
       chip_number as numero, 
       concat(firstname ," ", lastname) as nombres, 
       gender as genero, 
       chip_time as tiempo,
       time_format(sec_to_time(time_to_sec(chip_time) / 3.5),'%i:%s') as ritmo, 
       case photos when '' then '' else COncat("<button class=","submit-button-style"," onclick=","showPicture(['",photos,"'],",chip_number,");"," id=vtsphoto>Ver</button>") end as fotos,
       cert as certificado 
FROM db_vitalsports_web_online_results 
WHERE event_id = 585 and category like '% 3.5K'

/////////////////////////////////

now I have tried the simplest query

SELECT * FROM db_vitalsports_web_online_results

the error :

Hi Milos,

This is a customized table, in which I insert the data coming from xls files 

This is the dump table: https://drive.google.com/file/d/1IpzttOZIa-07ePAgWdE3qjuypQAvz9YI/view?usp=sharing

no positive results

I decided to create the most simple example, with 3.csv files that are attached and have issues with uploading the files. I don´t know where I am failing. I even removed the plugin and installed it again.

I am working in my WAMPP environment in my laptop to not affect the upgrade development to the production env for the client, could it be the issue?
