What would we do if the server throws an issue ‘Missing Controller issue for accessing the folders or files in the web’?
If the server is reporting issue as “Missing controller” for accessing the files or folder in the webroot directory. first check whether the htaccess file is having the appropriate default value which is suggested by the cakephp.
If .htaccess file is correct means, then its better to check the file permission be sure it is as 755, most importantly the group and world should not have the write access.
If the problem is still unsolvable please check the server log for further reference, it may give a clue to solve the issue.
