Laravel redirect() issue


If ELB pass 443 port to 80 port of the web server inside, and disable 80 port on ELB, redirect() will cause problem. Because redirect() always redirect pages to http and it will not display.

Pass full URL to redirect() function instead of URI only.

Notes for installation:

  5. Make sure extension “mbstring” and “exif” is enabled in php.ini

Helper to get thumb:


  1. Main view of File Manager is “\vendor\unisharp\laravel-filemanager\src\views\index.blade.php” and it uses some helpers of laravel like url(), asset(). If you use https only, these helpers will cause error. Try to overwrite Laravel helpers will solve these problems.
