Don't know what happened with my database (MySQL). The problem happens to my moodle 3.6. Today, I tried to install moodle 3.7, and when I tried to view the tables with phpMyAdin, I got the following error report. The problem doesn't not happen to all tables but only to some.
It seems that something wrong with my IIS7.5 or php7, or something else.
Can anyone help me? Thank you very much.
