Deactivation creates fatal error

Here’s a screen shot of the fatal error message that appears instead of my blog posts :

The easiest way would be to open the functions.php file from your child theme (the path is displayed in the error message) and comment out the relevant line (19) or lines (if there’s more code referencing WooCommerce). Without seeing the functions.php file it’s difficult to say what exactly needs to be commented out*. By doing this you can then uncomment out the relevant lines if you ever want to reactivate WooCommerce.

*To comment out use double forward slashes // at the beginning of every line that you don’t want to be processed (or /** PHP code **/ for larger sections of code). There’s a good blogpost about such things here.

Thanks for taking the time to reply purbeckpixels.

However, I’m still stumped.

Line 19 of my child theme functions.php file has nothing to do with Woocommerce. It’s important styling code for my English & French blog headers.

Here what lines 16 to 25 look like:

// Hides Header but displays Topbar
// on Single & FR Blogue page & EN Blog page.
function hide_header_single_posts() {
  if ( (is_single() && !is_product()) || is_page (649) || is_page (2177) ) { // Custom header for posts
    add_filter( 'fl_fixed_header_enabled', '__return_false' );
    add_filter( 'fl_header_enabled', '__return_false' );
    get_header();
  }
}
add_action( 'fl_body_open', 'hide_header_single_posts' );

I really, really don’t think commenting out any of these lines is a good idea. This code was all created way before I even installed Woocommerce plugin.

Any other ideas anyone??

Try this:

// Hides Header but displays Topbar
// on Single & FR Blogue page & EN Blog page.
function hide_header_single_posts() {
  if ( (is_single() /* && !is_product()) */ || is_page (649) || is_page (2177) ) { // Custom header for posts
    add_filter( 'fl_fixed_header_enabled', '__return_false' );
    add_filter( 'fl_header_enabled', '__return_false' );
    get_header();
  }
}
add_action( 'fl_body_open', 'hide_header_single_posts' );

Oops… don’t try that, try this:

// Hides Header but displays Topbar
// on Single & FR Blogue page & EN Blog page.
function hide_header_single_posts() {
  if ( /* ( */ is_single() /* && !is_product()) */ || is_page (649) || is_page (2177) ) { // Custom header for posts
    add_filter( 'fl_fixed_header_enabled', '__return_false' );
    add_filter( 'fl_header_enabled', '__return_false' );
    get_header();
  }
}
add_action( 'fl_body_open', 'hide_header_single_posts' );

Thank you again Purb.

Your code didn’t work but you did put a tech from my theme support team on the right trac.

The solution consisted in changing the function calls is_product() to is_singular(‘product’) under LINES 19 and 31 of functions.php

I have been able to deactivate WooCommerce and WooCommerce multilingual without creating a fatal error. ??

Forums like these are really awesome! Thank you again!

You’re welcome. Like I said, without seeing the complete functions.php file it was difficult to narrow down. It’s good that the theme author fixed it properly – commenting out all references to WooCommerce variables would’ve been just a quick fix, certainly not the best/correct way to do it.

I agree, these forums are a brilliant resource.
