Title: Custom Post Type Error Last modified: November 3, 2019 --- # Custom Post Type Error * [WPuser_Robin](https://wordpress.org/support/users/wpuser_robin/) * (@wpuser_robin) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/) * Hello, * I created a custom post type some time ago. Recently, when I request to display a specific category (associate, residential, commercial) the page returns: * > Error thrown > Call to a member function is_singular() on integer * What is my error and how can I fix it? * Thank you for reading my post! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcustom-post-type-error-8%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 8 replies - 1 through 8 (of 8 total) * [Ken Gagne](https://wordpress.org/support/users/kgagne/) * (@kgagne) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/#post-12092151) * How did you create the CPT — and how are you displaying it? * [Howdy_McGee](https://wordpress.org/support/users/howdy_mcgee/) * (@howdy_mcgee) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/#post-12092309) * Where does this error show up and what does that block of code look like? * If it’s in a theme and you’re unsure of theme development you may have to contact the theme author. * If it’s in a plugin you will have to contact the plugin authors. * Thread Starter [WPuser_Robin](https://wordpress.org/support/users/wpuser_robin/) * (@wpuser_robin) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/#post-12092628) * > How did you create the CPT — and how are you displaying it? * [@kgagne](https://wordpress.org/support/users/kgagne/) * Thank you for your response! * First, I need to apologize. I stated I created the CPT. I did not. A WordPress developer did. I have a ping to him for additional information. (I attempted to correct my post but found no option where I could.) * Second, I am unsure on how to respond to your second question. It is being displayed at the link I provided. If this does not answer your question, please let me know. * Thanks again! * Thread Starter [WPuser_Robin](https://wordpress.org/support/users/wpuser_robin/) * (@wpuser_robin) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/#post-12092640) * > Where does this error show up and what does that block of code look like? > If it’s in a theme and you’re unsure of theme development you may have to contact > the theme author. > If it’s in a plugin you will have to contact the plugin authors. * [@howdy_mcgee](https://wordpress.org/support/users/howdy_mcgee/) * Thank you for your response! * The error appears when you request to display one of the three categories at the top of the paged I linked in my original post. The error code appears on the page that is suppose to display the one category. Does this answer your question? * I do not believe the error is part of the theme because the theme was installed sometime before the CPT was created and theme does not offer the ability to create a CPT. * And I do not believe the error is due to a plugin because if it was, there is not plugin installed that gives the ability to create CPTs. * FYI, I have a ping into the person who created the CPT for additional information. * Thanks again! * [Howdy_McGee](https://wordpress.org/support/users/howdy_mcgee/) * (@howdy_mcgee) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/#post-12092642) * I see it now when clicking a category. This will surely require developer intervention and not something that is easily fixable from a user standpoint. Whenever the developer enables debugging it should let them know where exactly the issue lies( what PHP file and what line ). * One thing you may want to try is head to WordPress Admin -> Settings -> Permalinks- > and simply click the blue save button. This will refresh the permalink, likely won’t solve the issue but worth a shot. * Thread Starter [WPuser_Robin](https://wordpress.org/support/users/wpuser_robin/) * (@wpuser_robin) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/#post-12092657) * > I see it now when clicking a category.

Do you know how I can identify which line of code where the error resides? * FYI, I tried refreshing the permalink and no change. * [Howdy_McGee](https://wordpress.org/support/users/howdy_mcgee/) * (@howdy_mcgee) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/#post-12092667) * If you’re not familiar with PHP I wouldn’t suggest messing with the files. If you find you need to make a child theme and you do not, your changes will be overridden whenever the theme updates. * That being said… If you enable [WordPress Debugging](https://wordpress.org/support/article/debugging-in-wordpress/)( especially `WP_DEBUG_LOG` and check `wp-content/debug.log` ) then that error may tell you specifically what file and line the issue originates. * An easier solution may be to contact a local developer at a [local meetup](https://www.meetup.com/topics/wordpress/) or [local WordCamp](https://central.wordcamp.org/schedule/), possibly your host and see if they can fix this issue. * Thread Starter [WPuser_Robin](https://wordpress.org/support/users/wpuser_robin/) * (@wpuser_robin) * [6 years, 7 months ago](https://wordpress.org/support/topic/custom-post-type-error-8/#post-12092673) * > If you’re not familiar with PHP I wouldn’t suggest messing with the files. > If you find you need to make a child theme and you do not, your changes will > be overridden whenever the theme updates. > That being said… If you enable WordPress Debugging ( especially WP_DEBUG_LOG > and check wp-content/debug.log ) then that error may tell you specifically > what file and line the issue originates. > An easier solution may be to contact a local developer at a local meetup or > local WordCamp, possibly your host and see if they can fix this issue. * [@howdy_mcgee](https://wordpress.org/support/users/howdy_mcgee/) * Thank you! Your information was very helpful. * Have a great weekend!
