Responsive FileManager

[asemion]

I have the latest Get Simple version and site is running on my macbook webserver with php 7.1.16

Error: "Couldn't open /Library/WebServer/Documents/liisasavolainen/plugins/responsivefilemanager/config/config.tmp"

Hi, Acenda.
I do not know why on your site RFM look for file config/config.tmp
In this folder should be only config/config.php which using as plugin configuration parameters file.
I never have Mac PC maybe problem is there...
Try to copy config/config.php as config/config.tmp if it helps.
If not help I would suggest not use MAC PC as localhost, try to use real server on Unix, Linux or Windows on which RFM works without problem.
