Hi there, have you installed latest version of the theme? Flatsome 2.5.3?

Also, getting this error in logs when attempting to hit the wp-activate page, which is blank (example: http://alpinescience.com/wp-activate.php ) [17-May-2015 19:13:44 UTC] PHP Fatal error: Call to undefined function is_shop() in /home/alpinesc/public_html/wp-content/themes/flatsome/inc/template-tags.php on line 657

Hi there, we’ll take a look and have it fixed asap. It should work if you activate WooCommerce pr site “PHP Fatal error: Call to undefined function is_shop() in /home/alpinesc/public_html/wp-content/themes/flatsome/inc/template-tags.php” is happening because WooCommerce is not installed. You could add it as a “Must use plugin”: https://codex.wordpress.org/Must_Use_Plugins

It doesn’t work even if woocommerce is enabled … here is our main site with woocommerce enabled: http://alpinescience.com/wp-activate.php .... still get blank page …. we don’t get the blank page when we disable Flatsome ….

Hi again, do you have latest version of the theme installed?

The function in tempalte-tags.php should look like this:

if(ux_is_woocommerce_active()){
    if($flatsome_opt['category_row_count'] == '1' || is_shop()){
       add_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_single_excerpt', 30);
    } else if($flatsome_opt['short_description_in_grid']) {
       add_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_single_excerpt', 30);
    }
}

It checks if WooCommerce is active before running that function.

Yes, we’re running 2.5 and it has that in template-tags.php. It also fails on your demo as well: http://flatsome.uxthemes.com/wp-activate.php ... even though you aren’t on multisite, WP has wp-activate.php by default and should take users to wp-login.php?registration=disabled with a login screen and the message that “user registration is disabled” .. here’s an example: wptavern.com/wp-activate.php …. This used to work on Flatsome, btw ….

Hi again, thanks for noticing. I think I found a solution. Try change that code to this:

/* Show short description in grid */
if(ux_is_woocommerce_active() && function_exists('is_shop')){
    if($flatsome_opt['category_row_count'] == '1' || is_shop()){
       add_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_single_excerpt', 30);
    } else if($flatsome_opt['short_description_in_grid']) {
       add_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_single_excerpt', 30);
    }
}

Basically just change this:

if(ux_is_woocommerce_active()){

to this:

if(ux_is_woocommerce_active() && function_exists(‘is_shop’)){

Thank you. That allows some code to load when viewing page source (none loaded prior to this change), but we still have a blank white page: http://alpinescience.com/wp-activate.php

Better yet, here’s a site we just registered and this is the exact link that is clicked from the confirmation email that yields the white confirmation page: http://test33.alpinescience.com/wp-activate.php?key=2dce41f290dfca30

Could you try enable the wp_debug? That should give you an proper error message instead of a white screen.

This is the error: Notice: Undefined property: stdClass::$public in /home/alpinesc/public_html/wp-includes/ms-settings.php on line 184 Fatal error: Call to undefined function is_product() in /home/alpinesc/public_html/wp-content/themes/flatsome/inc/extras.php on line 52

Try change line 49 in extras.php to this: if(ux_is_woocommerce_active() && function_exists(‘is_product’)){

It’s 47 in my extras.php … then I get this error: Fatal error: Call to undefined function get_product_search_form() in /home/alpinesc/public_html/wp-content/themes/flatsome/inc/shortcodes/search.php on line 16

Good deal, that seems to get the trick done! The widgets don’t quite work at bottom of the page, but we just need activations to work, so this is great! It would be nice to be able to style it but it looks like WP core doesn’t have a CSS container for wp-register or wp-activate … so it is what it is! Thanks for your help! ... http://alpinescience.com/wp-activate.php

Aweseome:) This fix is included in latest version of the theme that was released yesterday

Looks like some of the fix wasn’t in the update as I just uploaded update and registration functionality was immediately broken after the update …. only the header loads …. will have to go through this message again in the AM and reapply all the fixes …

What does the debug message says?

No message when debug enabled but error log has this: [21-May-2015 08:01:12 UTC] PHP Fatal error: Call to a member function get_cart_url() on a non-object in /home/alpinesc/public_html/wp-content/themes/flatsome/header.php on line 93

I just realized that today we turned on “SHOW MINI CART” to “Top Right” in header settings, so that is the trigger for error and have confirmed turning that mini cart off makes wp-activate.php work again …

Somehow WooCommerce is activated but never loaded if you run wp-activate.php. That’s why the error messages is there. Could you try network enable WooCommerce?

Theoretically, yes. But then we would have a bunch of confused users and support tickets about why, how and what woocommerce is, higher potential for plugin conflicts on those sites, potential issues with themes that are not woocommerce friendly and unnecessary resource usage on page loads …

Hi there, I think you have a problem with a plugin. Could you test disable some plugins and check if it helps?

I disable plugins and test but still the problem exist.
