Configure button not responding

pro-tip; you can disable Autoptimize on a per-request basis by adding ?ao_noptimize=1 to the URL.

if the problem is not there at that point, some autoptimize (re-)configuration might be needed to fix this. there are troubleshooting tips and info on how to exclude in the AO FAQ.

hope this helps debugging,

Still no effect, although a bit different errors

again a weird issue as PC_Config is defined in the inline JS (which, if I am not mistaking, you were not aggregating?).

If I turn off the Autoptimize plugin everything works fine.

disabling JS optimization or JS aggregation will probably also work.

Can we consider that this is the fault of the Autoptimize plugin?

well, it does work with AO for marcusig, so it looks like something else might be in the mix here ..

As in that case I would suggest to close this thread and continue under Autoptimize support.

I would provide the same answers there as I do here 🙂

now if the whole exclusion trial-and-error process is not leading anywhere (or if you want a simpler solution), one can easily disable Autoptimize being active on a specific page, e.g. with below code snippet for your current page:

add_filter('autoptimize_filter_noptimize','kacor_noptimize',10,1);
function kacor_noptimize( $flag_in ) {
    if ( strpos( $_SERVER['REQUEST_URI'], 'product/testtest/' ) !== false ) {
        return true;
    } else {
        return $flag_in;
    }
}
