I am using a modded version of an unsupported Theme (zp-skeleton)
and find following errors in my servers php_error.log
PHP Notice: Undefined variable: zpskel_ismobile in /xxx/html/zp-core/template-functions.php(4451) : eval()'d code on line 2
I am using Zenphoto 1.4.10
I would like to keep using this theme, as everything works fine.
How to change my modded theme to get rid of the errors?
How to define a undefined variable?
