I used to work with limesurvey 5.2.6 on windows on localhost and everything was going fine (I use XAMPP with modules Apache and MySQL).
I recently updated limesurvey to version 5.2.7. I proceeded to the installation, the authentification, and got access to the main menu without any problems.
But when I click on "list available surveys", I get this server error :
I found the table limesurvey_groups in my SQL database but I don't know what "limesurvey_groups.MYI" refers to. Could someone give me a hand with that problem ?
