Hello Ian,
Thanks for getting back to me quickly.
My server runs PHP version 5.6.23 for information.
I knew my query was at fault when the site crashed but I was surprised to hear your plugin was incriminated. I installed it and created a couple tables with sql queries but since I couldnt do what I wanted (I needed very complex formatting that could only be handled by a specific function), I deleted the tables but left the plugin activated. So yes, it doesnt make sense that it was called when I triggered my shortcode.
You dont have to apologize, you are offering a good service for free and in those cases mistakes can happen. That’s why I tried to contact you in private at first because I didnt want to post that in a public place because it might hurt your plugin’s reputation when it may be a problem that is specific to my setup. But when people see how fast you replied and that you cared I think they’ll forget about it!
Best regards,
Cedric
