the system used to work correctly, but then this error occurs I had no idea for the solution since i'm still new to this platform; but I've checked similar issue that suggested its due to missing file directory. Any suggestion?
Attached is the File structure; These files are under a system fileFiles structure
This occures due to the following reasons.
your system folder might be missing
Check your permission of folders
Open your index.php file and find $system_path and
$application_folder.
$system_path = 'system';
$application_folder = 'application';
