Hi guys, anyone know how to fix this. I was cleaning my keyboard awhile ago. I accidentally press something and this happen. I try to undo it but not working and trying to find solution on internet but still none explain my situation. For your information, I'm not a app user , its just my university use it for providing all the learning materials.
Can not think of how this could happen by accident, unless you were editing the config.php file at that time. In case, check your config.php file. I have posted details in this thread: https://moodle.org/mod/forum/discuss.php?d=391991&parent=1580896.
