Hi,
I just install the quickselect field in my project : site/plugin/quickselect/quickselct.php
And I got a message error on my whole panel : Class ‘SelectField’ not found
It comes from this line of the plugin :
3. class QuickselectField extends SelectField {
I’m using kirby 2.5.5, havent this issue on 2.4, I will try another plugin to see if I have the same problem.
