FAQ

Have some configuration file?

No, are just functions for developers and coders, see k1-functions.php to get more info.

For TIMTHUMB see: https://www.binarymoon.co.uk/2012/03/timthumb-configs/. But, it supposed to work as is now.

images are not displayed !

Normally is permission problems. Please try 766 permissions on {wordpress plugins path}/k1-functions/tools/timthumb/cache. There will be the “small” copy of every img resized by this function.
If not, Left click on the img, COPY the URL and see the error on the browser, probably you will know what to do.

The FOLDER “cache” must have write access any way.
