It might be an issue caused by a plugin or your theme. I recommend installing this plugin: [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/) After you install and activate the above plugin it has a Troubleshooting mode which allows you to have a vanilla WordPress session, where all plugins are disabled, and a default theme is used, but only for your user – your visitors will still see the normal website. * Go to its troubleshoot mode and only activate Strong Testimonials and see if it works correctly with a default WordPress theme (Twenty Nineteen for example) and no other plugins. * Please let me know how it goes and what you find! * All the best, Marian * Thread Starter [tonylees00](https://wordpress.org/support/users/tonylees00/) * (@tonylees00) * [5 years, 7 months ago](https://wordpress.org/support/topic/error-when-adding-new-testimonial/#post-13585532) * Hi Marian, * Ok, I have installed the plugin and caried out the actions you mention, and I have the same result. * I did find that this is in debug mode – with debug disabled it works ok, but I am concerned this is only hiding the issue. * Thanks Tony * [visi19](https://wordpress.org/support/users/visi19/) * (@visi19) * [5 years, 7 months ago](https://wordpress.org/support/topic/error-when-adding-new-testimonial/#post-13590799) * Hello [@tonylees00](https://wordpress.org/support/users/tonylees00/) * Thanks you for reaching us ! * So if you don’t have any plugin other than Strong Testimonials installed with theme default do you have any problems? (ie an error will appear) if no error occurs it means that it is a problem brought by a conflict between plugins, if there is a problem when only strong testimonials on theme default is installed then it is a problem from us. Can you send us a URL link to your website? * Please let me know if you have some more questions ! * Have a nice day ! 🙂 * Warmly, Marian * Thread Starter [tonylees00](https://wordpress.org/support/users/tonylees00/) * (@tonylees00) * [5 years, 7 months ago](https://wordpress.org/support/topic/error-when-adding-new-testimonial/#post-13591595) * Hi Marian, * The site can be found at upvcsuppliesdirect.co.uk * The issues still occur with only Strong Testimonials activated. Please note the errors only she with debug set to true. * Thanks Tony * [visi19](https://wordpress.org/support/users/visi19/) * (@visi19) * [5 years, 7 months ago](https://wordpress.org/support/topic/error-when-adding-new-testimonial/#post-13600993) * Hello again [@tonylees00](https://wordpress.org/support/users/tonylees00/) * The problem has been solved because those variables have been set, after the update the problem will be solved. We don’t know exactly an exact date for the update yet.
