Enable the exif extension in your php config
Thanks man
@danrovito Hi. I'm facing this problem now. How can I edit exif? I found them in php.ini but what should I do with this? Is there a value I should change? And what is the effect when I change it? Thanks a lot.
In you php.ini. It is commented by default, just uncomment it. Then restart you web server
@flashery There are many exif options there, which one should I uncomment?
extension=php_mbstring.dll
extension=php_exif.dll
@pranayaryal These two options are already enabled.
Then restart your webserver
What is the output of running php ./vendor/unisharp/laravel-filemanager/bin/debug in your project directory.
I also had to do brew install php70-magick
Then restart server
See this link also https://github.com/UniSharp/laravel-filemanager/issues/475
I have already restart my server. Exif is now enabled but still getting the same error. Please see the image below

@jonjie0317 Have you tried @pranayaryal instruction? Run thisphp ./vendor/unisharp/laravel-filemanager/bin/debug and paste the output here so we can help.
Hi @pranayaryal @flashery Please see the output below: (Thanks)

So looks like imagick php extension is not installed.
You can do a google search and install it for windows. I am not sure what to do for windows. I installed on mac.
@pranayaryal Hi. May I ask one more question? What is imagick php extension for?
