Can you provide me some more information? For example which browser you use, does this Notice show in every browser? the fastest way to contact me is to send me an e-mail through the form on my website. * The easiest way for the moment is to disable the PHP error reporting on your hosting account. You can ask you hosting provider about this. * Thread Starter [AnaBelenRoMar](https://wordpress.org/support/users/anabelenromar/) * (@anabelenromar) * [8 years, 3 months ago](https://wordpress.org/support/topic/undefined-index-http_referer-3/#post-10060395) * Hi Frank, * The code in my theme is: do_shortcode(‘[wps_login]LOGIN MODAL[/wps_login]’) * I tested it in: Windows: Google Chrome: Versión 64.0.3282.186 (Build oficial)( 64 bits) Internet Explorer : version: 11.0.9600.18816 Firerox Quantum: 58.0.2( 64-bit) Android: Google Chrome, * And the mistake is the same: * Sign in to your account Notice: Undefined index: HTTP_REFERER in /home/spaceint/ public_html/lilouli.com/ab-plagins/wpstudio-login-modal-box/inc/glmb-frontend. php on line 35 * Tell me if you need something more. * Thread Starter [AnaBelenRoMar](https://wordpress.org/support/users/anabelenromar/) * (@anabelenromar) * [8 years, 3 months ago](https://wordpress.org/support/topic/undefined-index-http_referer-3/#post-10060437) * I have more information, the mistake is when “Page After Login” or “Page After Logout” is not empty. * If “Page After Login” and “Page After Logout” are both empty, there is no mistake. * Thread Starter [AnaBelenRoMar](https://wordpress.org/support/users/anabelenromar/) * (@anabelenromar) * [8 years, 2 months ago](https://wordpress.org/support/topic/undefined-index-http_referer-3/#post-10123457) * Hi Frank, I have the solution… It is a simple if in your code. 🙂 * The error is when the “HTTP_REFERER” value is not definined. If you want to reproduced it, you need to open a new tab clean and put the url to want to login. * Please tell me if you have any problem. * Thks. * [DavidPeralvarez](https://wordpress.org/support/users/davidperalvarez/) * (@davidperalvarez) * [8 years, 1 month ago](https://wordpress.org/support/topic/undefined-index-http_referer-3/#post-10243876) * Same problem here.

He answered to me “When I find the time I will have look at this”. * The mistake is when you open a new tab clean, put the url of your web, and click to login. If you want to solve the problem, you only need to disable the PHP error reporting, in your wp-config. For this reason, don´t worry, when you are in production you will not have this error. * I hope I helped you. * [DavidPeralvarez](https://wordpress.org/support/users/davidperalvarez/) * (@davidperalvarez) * [8 years, 1 month ago](https://wordpress.org/support/topic/undefined-index-http_referer-3/#post-10246920) * Hi again Ana, * Ok, great thanks a lot for your answer.
