return 500 when uploading image in browser

[piliplaker]

I installed pictshare on my vps by unpacking the zip file. And I use caddy to host the site.

related part of configuration like this:

xxx.xxx { root /var/service/pictshare log /var/log/caddy/xxx.xxx.log errors /var/log/caddy/xxx.xxx..log.error fastcgi / unix:/var/run/php/php7.2-fpm.sock php }

and when the error happened , an error log shows like this.

29/Dec/2018:09:06:40 +0000 [ERROR 0 /api/upload.php] PHP message: PHP Warning: fopen(/var/service/pictshare/api/../data/sha1.csv): failed to open stream: No such file or directory in /var/service/pictshare/inc/core.php on line 360 PHP message: PHP Fatal error: Uncaught Error: Call to undefined function mb_strlen() in /var/service/pictshare/inc/core.php:313 Stack trace:

3 {main}

thrown in /var/service/pictshare/inc/core.php on line 313

what should I do ?

You need to install php7-mb so the multi byte functions are found. Will update Readme
