Title: ReferenceError: inc_opt is not defined Last modified: December 4, 2018 --- # ReferenceError: inc_opt is not defined * Resolved [Martina Maurer](https://wordpress.org/support/users/la-stria/) * (@la-stria) * [7 years, 6 months ago](https://wordpress.org/support/topic/referenceerror-inc_opt-is-not-defined/) * Hi * My Hustle stopped working and none of my tests to fix it worked so far. It’s been a while like this, so I don’t know what we changed at that time it stopped for sure, but in hope to remove incopabilities, I now switched many plugins to WPMU DEV ones (Defender, Hummingbird, Smart Crawl and Smush). However I still do have a JS error message coming (if I’m not mistaken) from the hustle directory: / wp-content/plugins/wordpress-popup/assets/js/front.min.js?ver=1.1 * Tests I did so far without success: – Deactivated all other plugins than Hustle– Added an embed on another site – Reinstalled Hustle – Switching to another theme * Only thing that worked: – Added a new site to the network with another theme * Can you please help me? * Best regards * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Freferenceerror-inc_opt-is-not-defined%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 7 replies - 1 through 7 (of 7 total) * [Predrag – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support1/) * (@wpmudev-support1) * [7 years, 6 months ago](https://wordpress.org/support/topic/referenceerror-inc_opt-is-not-defined/#post-10953662) * Hi [@la-stria](https://wordpress.org/support/users/la-stria/), * Sorry to hear you’re having issues with Hustle 🙁 * Could you give me some more info about the issue you are having, are you unable to edit/create popups/slide-ins or they are not shown on frontend? * Also, could you tell me a bit about your setup, which WP and PHP versions you are using and also which browser and OS (and their versions) are you using? * Cheers, Predrag * Thread Starter [Martina Maurer](https://wordpress.org/support/users/la-stria/) * (@la-stria) * [7 years, 6 months ago](https://wordpress.org/support/topic/referenceerror-inc_opt-is-not-defined/#post-10953894) * Heya * Ah, yes.

They are not shown. * PHP Version: 5.6.38 WordPress Version: 4.9.8 Hustle Version: 6.0.5 * I’m testing on Chrome (71.0.3578.80), Firefox (63.0.3), Internet Explorer (11.407.17134.0) and Edge (42.17134.1.0). None of them shop the currently active Slide-in. * Could it be PHP is not in 7.2 yet? * Thread Starter [Martina Maurer](https://wordpress.org/support/users/la-stria/) * (@la-stria) * [7 years, 6 months ago](https://wordpress.org/support/topic/referenceerror-inc_opt-is-not-defined/#post-10954100) * Updated to PHP 7.2 now.

Add these lines in the wp-config.php file: * ``` define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false ); ``` * Please make sure that you insert these lines above `/* That's all, stop editing! Happy blogging. */` in the wp-config.php file. * Please refresh the front end, if there will be errors, these will be saved in the debug.log file inside the `/wp-content/` directory. * Please check the debug.log and let us know if there will be errors. * Cheers, Nastia * Thread Starter [Martina Maurer](https://wordpress.org/support/users/la-stria/) * (@la-stria) * [7 years, 6 months ago](https://wordpress.org/support/topic/referenceerror-inc_opt-is-not-defined/#post-10956795) * Good morning * Thank you for your help.
