Title: Undefined variable?

I can’t provide a direct link to the site I’m working on because it’s under maintenance. * Notice: Undefined variable: spc_output in /home/content/p3pnexwpnas02_data02/ 49/2189949/html/wp-content/plugins/show-post-categories/includes/category.php on line 90 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fundefined-variable-53%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 9 replies - 1 through 9 (of 9 total) * Plugin Author [willemso](https://wordpress.org/support/users/willemso/) * (@willemso) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10031003) * Hi awholelotofnothing * Could you say what version you are currently using? Also, please post the shortcode causing the issue. * Thread Starter [awholelotofnothing](https://wordpress.org/support/users/awholelotofnothing/) * (@awholelotofnothing) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10032660) * Version 2.2.33 * [show_post_categories show=”category” parentcategory=”Heat Rating” parent=”no” hyperlink=”yes”] * Thanks! * Plugin Author [willemso](https://wordpress.org/support/users/willemso/) * (@willemso) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10033590) * Hi awholelotofnothing * could you tell me if your shortcode is entered by using some pagebuilder, or by using the default WP Visual/Text editor? * In the above code there is a double quote: ” (in unicode that´s [U + 201D](https://www.compart.com/en/unicode/U+201D)) where it should be ” instead (that´s in Unicode [U + 0022](https://www.compart.com/en/unicode/U+0022) or in ASCII that´s ALT + 34). * I tried your code in my Dev kit with v2.2.33 and it worked as expected. Try to copy this code instead;`[show_post_categories show="category" parentcategory=" Heat Rating" parent="no" hyperlink="yes"]` * If this does not work, could you remove SPC completely and install the developers edition? Go to [the bottom of this page](https://wordpress.org/plugins/show-post-categories/advanced/) and select “Development version”, download the zip & Upload it to your plugins. Activate it and try again.. * _note; the developers version is untested, but I am sure the category part will work fine._ * Now if still experiencing issues, could you provide me with a screenshot of the linked categories? In that cas I´ll simulate some more using your exact scenario. * Keep me posted! * Thread Starter [awholelotofnothing](https://wordpress.org/support/users/awholelotofnothing/) * (@awholelotofnothing) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10033680) * I tried deleting then installing the developers version and am still getting the same warning. I also tried using raw HTML as opposed to WYSIWYG Text to add the code. I’m using WP Bakery but I disabled it to enter the code you provided using the default WP Text editor. * Which linked categories do you need? [These are the child categories](https://www.dropbox.com/s/3ks4d77gw5swjmm/Screenshot%202018-03-02%2016.31.20.png?dl=0) of the Heat Rating category I sent upthread. * Thanks! * Plugin Author [willemso](https://wordpress.org/support/users/willemso/) * (@willemso) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10033734) * Hi, * I think it might be some conflict between SPC & WP Bakery since I am unable to simulate it.. * Could you try by only using `[show_post_categories show="category"]` * If this works, add the attributes one by one just to see if it breaks in a specific situation? * Also, do you remember if the issue started after upgrading to 2.2.33? * Thread Starter [awholelotofnothing](https://wordpress.org/support/users/awholelotofnothing/) * (@awholelotofnothing) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10033779) * I used the plugin on a development version of the site using WP Bakery several months ago without issue. Maybe the new version of the SPC plugin has some kind of glitch? * I tried [using the shortcode](https://www.dropbox.com/s/q324nq3ns4u64b4/Screenshot%202018-03-02%2017.04.19.png?dl=0) you provided and it gives every category for the post as it should but with the same error. * Plugin Author [willemso](https://wordpress.org/support/users/willemso/) * (@willemso) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10033907) * ok, I think I might have a lead. Could you once again remove SPC & reinstall the dev version? * I just updated some coding in the category part that might fix it. So make sure you download the new available developers version 🙂 * Thread Starter [awholelotofnothing](https://wordpress.org/support/users/awholelotofnothing/) * (@awholelotofnothing) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10033925) * It worked! Thanks so much! * Plugin Author [willemso](https://wordpress.org/support/users/willemso/) * (@willemso) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10033977) * **Great!** It will be about a week before you’ll see an update notification ( 2.2.34) that will bring you back to the stable release. * I hope this also fixes your previous issue. In case there are no more issues I’ll close this topic. Also, if you like using SPC a small review keeps us going 😉 Viewing 9 replies - 1 through 9 (of 9 total) The topic ‘Undefined variable?’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/show-post-categories_446def.svg) * [Show Post Categories](https://wordpress.org/plugins/show-post-categories/) * [Frequently Asked Questions](https://wordpress.org/plugins/show-post-categories/#faq) * [Support Threads](https://wordpress.org/support/plugin/show-post-categories/) * [Active Topics](https://wordpress.org/support/plugin/show-post-categories/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/show-post-categories/unresolved/) * [Reviews](https://wordpress.org/support/plugin/show-post-categories/reviews/) * 9 replies * 2 participants * Last reply from: [willemso](https://wordpress.org/support/users/willemso/) * Last activity: [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-53/#post-10033977) * Status: resolved
